Sir, I am very lucky that I am born in the same era where the greatest teacher of the world Sir H C Verma is also born. I grew up reading your concepts of Physics in the year 1997 when I was in class 11 and the same book is kept with all care and now my son studies from the same book who is in class 11. I have deep love and respect for you sir. You have made Physics so much lovely and enjoyable. My Pranam 🙏

[@AkshatNh744]

Sir my name is Akshat I am from class 10th I am always confused that why an ammeter is connected in series and a voltmeter is connected in parallel also why the current divides in parallel connection and voltage divides in series connection, I have heard that the current always travels the shortest path so why does the current travels through our body (with high resistance) when we touch a live wire why does it not travels through the copper wire only isnt it the shortest path ??

[@uttu2008]

Cuz the current will travel through shortest path, low resistance and high potential difference. If the current passes through our body it will directly reach the earth, which as 0 potential. That's why

[@garvitagarwal56]

BECAUSE IF WE CONNECT VOLTMETER IN SERIES THEN VOLTAGE GOT DIVIDED ON THE CONNECTED COMPONENTS EX BULB SO VOLTMETER WILL NOT BE ABLE TO MEASURE THE ACTUAL POTENTIAL DIFFERENCE SAME WITH THE AMMETER IN PARALLEL CURRENT GET DIVIDED IN BRANCHES OF THE SYSTEM IF WE CONNECT AMMETER IN PARALLEL THEN IT IS NOT ABLE TO MEASURE THE ACTUAL CURRENT AND REST OF YOUR QUESTION REGARDING THE CURRENT FLOW THROUGH BODY AS WE KNOW CURRENT FLOW DUE TO POTENTIAL DIFFERENCE i.e. is voltage and as current cannot flow from lower potential difference to higher potential difference so it flow through our body as we are connected to earth potential is considered to be zero so thats why current flow through body not flow back in copper wire i hope you are ablee to understand it

[@garvitagarwal56]

ok

[@uttu2008]

Ammeter is connected in series cuz it measures current which is constant along series. Voltmeter is connected in parallel cuz it measures voltage which is constant along parallel

[@suraj-ug8mj]

I respect you for how simple and accurate you've made physics. But what do you mean single particle? Single particle would mean a blackhole. because a point is considered as small as planck's length . A point at which all mass concentrates is a blackhole essentially. Had we considered a sphere of certain radius greater that schwar..radius, then that sphere would have meant to be a centre of mass that can behave physically consistent with the motion of the rotating object.

[@adityaroy-zg8xw]

Tangent should be defined for direction

[@chitraR._holistic]

As a 10 class student.... Keep compass on the north pole of magnet ... if we will mark the tangential direction it automatically will be going curved because South pole is also attracting that compass needle .....also there would be only one tangential direction of the figure formed hence it's a curve..... Hence it forms a loop ....also inside the magnets there are also magnetic lines helping it to become entire curve.... 🙏🙏

@@ExplorifyHub_ Bro as I told in above comment that these things are practical and if we will keep the compass obviously its tip of needle will be towards the north from the south and if we'll mark the tangential direction ofc it will be a curve moving south to north ..... We don't have proof of all these things coz they are practical things .... Rest, idk more than what I explained।।।।🙏🙏

[@khushiVerma82501]

Sir myself Khushi Verma I want to ask that while studying radiations If we consider the example of hotspot technique used in Test. Cricket matches to detect whether the ball has touched the bat or not, so when the ball approaches near to the bat isn't it possible that due to their high mutual attractive force of attraction as distance is very small the surface of bat gets heated up and liberates radiations which may get detected by the camera and converted into visible spectrum and misjudgement may be there?

[@JeeadvanceAIR1-m2h]

Sir I have a question does wave hav mass ???? (( If not then how they exert force and how they have momumentum ,and also by de brogli hypothesis particle can show wave nature so partical have mass means wave have mass ?????)

[@SwarajPawar-yx1dp]

You are correct , a particle having certain mass behaves like a wave (has wavelength) and waves like light and cathode rays have mass (thus KE). But a massive particle (let us consider a tennis ball) having more mass and low velocity compared to a photon or electron, has a negligible wave nature (this has near 0 chance of passing Young's double slit). Similarly a high velocity particle with negligible mass (what we consider as a wave) would have negligible particle nature (thus you won't feel like getting gunshot after pointing a laser beam on hand , that's negligible Kinetic Energy). Hope that clears the doubt.

[@apoorvvyas52]

Sir, please explain about rotational kinetic energy being zero. That question is left unanswered in your explanation.

[@pritampramanik1729]

In the example of coin flipping, you saw the motion called trans rotational. We can easily study the translational motion using COM. And for rotation we won't assume all masses concentrated at centre, rather it's a rigid body. We will study the motion with respect to COM which breaks down our problem to pure rotation. So the Rotational Kinetic Energy wrt COM isn't zero at all. It's (1/2 Iw²) , {I =1/4mr² for coin here}. There will be translational KE as well which is 1/2mv² & yes v is the velocity of centre of mass. Hope you got it :)

[@nilotpalpuzari]

Let's the radius of the coin be R, And we toss the coin in three ways A. Thumb is hitting the coin at 0.9R from center B. Thumb is hitting the coin at 0.5R from centre C. Thumb is hitting the coin at the centre Question: If the force of hitting the coin is same for all cases, will COM gain the same height in all three experiments? I think no, Because in A and B the coin will gain a rotational KE (as it will spin) in addition to its vertical translational motin. So the same energy will be used in both translational and rotational KE. Whereas in C the coin will not spin and and hence will attain max height. Am I right or I am not getting something?

[@xavier-bv6yd]

You are right but just missing a small point. Try to figure it out.

[@dindayalsingh1618]

I think it is torque which cause rotation not force so com will, have diffrent height due to diffrent value of torque

[@hcverma2928]

I am impressed by your logical thinking. However the initial energy is provided by you during the flicking. If you apply the force for a time dt, the displacement of the point of contact is different in the three cases. So they start with different total kinetic energies (rotational and translational). Finally they will reach the same height. Xavier-bv6yd: Sorry, I interrupted. You wanted Nilotpal to think more on it which is what I also generally do. But I knew that I will not come back to this post, so could not restrain responding. I rally liked Nilotpal's questioning spirit.
