[@utkarsh7225]

The question should be "Why the equilibrium is not reached by the almirah magnet system(at the point where the curves of the magnetic force and normal force by the clothes are coinciding each other) which is theoretically possible but why should we have to apply force on the almirah to get it into equilibrium?

[@sarthak8636]

I don't get your question plz tell me in simple Language 🙂

[@utkarsh7225]

@@sarthak8636 why we can't get the situation easily in which the force applied by the clothes on the almirah is equal to the magnetic force of magnet and almirah so that the almirah magnet system becomes in force equilibrium ? This situation is shown in the graph where the curves of the magnet force and curves of the normal force applied by the clothes on the almirah are touching each other .

[@prabaldeepdhawan329]

@utkarsh7225 initially, when the curves are coinciding, they are in equilibrium, however door is open, and won't move without external force...now to close the door, you need to apply some force, the force required will be less as long the spring and cloth forces coincide, now once the clothes come into picture you need to apply force high enough to overcome the "spring force" which is linear in nature due to clothes. Once distance reduces alot, the magnetic force itself will be come strong enough to overcome the force due to clothes. Please note that spring force is linear in nature where as, magnetic force increases inverse to cube of distance, hence at a farther distance force of clothes will dominate hence you need to apply extra manual force, but at a smaller distance magnetic force will dominate, so no need to apply external force

[@utkarsh7225]

@@prabaldeepdhawan329 Thanks for the answer but you have not explained the core question , "Why do we not get the situation in which the magnetic force is balanced by the (spring+normal) force practically?" Which can be experienced by applying a small force by your index finger which will not be able to move the almirah door.

[@Bēdguy69]

Sir, i have a question from Ray optics. Sir, According to Irodov, Power of curved surface =( refractive index of light entering medium - refractive index of light coming medium )/ radius of curvature of curved surface. If we apply this formula to thin lenses then Power of thin lens = Refractive index of lens/focal length But, According to your book Concepts of physics and NCERT ,Power = 1/f So which one is correct and which is not??

[@physicslover4203]

Actually thin lens has two curved surfaces and now power for first incident surface of thin lens is u2-u1/R1= now for 2nd curved surface of thin lens which is present on emerging side power is u1-u2/R2 now these two add give power of lens P =(u2-u1)(1/R1 -1/R2) now take u1 to left side then power is P/u1= (u2/u1-1)(1/R1 -1/R2) , now right side is equal to 1/f by lens maker formula . So P/u1= 1/f Actually power is not equal to 1/f it is equal to u/f and u is Refractive index of medium in which lens is placed (if it is air ) then only p=1/f ( specific case of air)

I am very confused about this question thanks for such a graye explanation

[@vivekbhawsar77882]

RESPECTED SIR, My Name is Anshu Bhawsar, I Am From Mandsaur MP My Question is as we know that varying Refractive index bends light cause of its speed change so can we intentionally change the refractive index in that manner that the wave nature of light can be converted to its particle nature and vice versa is it possible to do so.

[@aryanaman7]

what? light exist as wave and particle together and not interconverts and speed of light never changes, light is em wave and the atoms actually interact with the em part to vibrate and this produces a new wave which gets superpositioned with the original wave, the slowed down and bent part are two waves and not one and when light leaves that medium there is no atom anymore to produce the second wave so light regains its speed

[@vivekbhawsar77882]

@@aryanaman7 Buddy ! Go on google search this "why light bends in varying refractive index" and If the refractive index variation is that precise that it is comparable to that of wavelength of light so what is result than is it same

[@aatif3831]

Hello Anshu, Wave nature and particle nature are not two different things. Light (or any matter) always has a wave associated with it. Even you have a wave length! It's just that you're too big for your wave nature to show any significant effect. But at a scale that small the line is blurred, and all the particles exists in both the forms, simultaneously.

[@aryanaman7]

@@vivekbhawsar77882 buddy i already know why light bends and slows down in a medium, and what i explained is the reason light never really slows down but light consists of a electric field and a magnetic field and these fields put a force on atoms nearby and the atoms start vibrating, now since atoms are vibrating they are accelerating which in turn produce another wave slightly offset which when superimposed on the original wave makes it look bent and also slows it down, the slowed down wave is actually two waves and not one and when light leave the medium there are no more accelerating atoms so no new wave is produced and light continues in its original wave and this is the most modern accepted explanation, also how are you gonna compare dielectric to wavelength? the dimensions of wavelength and dielectric are totally different, and wavelength of electromagnetic wave can lie from a few nanometer to 100s of km so in what units are you gonna compare the both?

1.Archimedes Principle Says Weight of the displaced liquid = Buoyant force(in short). The concept of force was given by Isaac newton and weight is the gravitational force between earth and the concept of gravitational force was also given by newton. Archimides was born about 1900 years before newton so how force and weight are coming in his principle 2.About Floatation In terms of density Its derivation is as follows : For Flotaton: B>W Vp(liquid)g>Vp(object)g So Pl>po for floating. But Here is volume of Object and displaced liquid is taken same.It Is true for the case where object is fully immersed but it is not true for partially immersed object as it will displace liquid equal to the immersed part but weight of whole object is taken so the volume of whole object is taken.

My question - What is the significance of finding the sum and product of zeros of quadratic polynomial what does it represents geometrically or practically??

[@dhruvbaghel466]

Remember factorisation method to solve a quadratic equation? You used to multiple coefficient of x² and constant term in the equation and then use it to split the middle term as a sum? That's actually a general way of finding solutions of a known quadratic equation. And finding the equation if you know the solutions. The significance of this method is you can convert the general form of quadratic equation into "factor form". The factor form can be understood as a rectangle of sides of each factor term. And what should be the value of x so that the area of this rectangle becomes zero.

[@ritvikg]

Because in vector analysis ( vector spaces ) we need an identity element which is 0 and because we are talking about vector fields, we must call it a vector rather than just 0. Otherwise it doesn't matter at all. Or you can also see it as, only like quantities can add, you can't add a number to a vector, you need a vector for that, hence identity element is a 0 vector rather than just 0.
