no need to use uv method. when you differentiate x^3/3 it will come out to be 3x^2/3 so 3 and 3 will cancel and you will get x^2, uv method is only necessary for where there are variables in denominator also.

Solution to homework question: U = x³/3 - 4x + 8......(i) F net = 0 Therefore, -dU/dx = 0 Differentiating equation (i) we get... -(x² - 4) = 0 => x = +2 or -2 When x = +2, => d²U/dx² => d²(x² - 4)/dx² On differentiating it, we get.. => 2x => 2 × (+2) => 4 So, d²U/dx² > 0 U = minimum Stable equilibrium. When x = -2, => d²U/dx² => d²(x² - 4)/dx² On differentiating it, we get.. => 2x => 2 × (-2) => -4 So, d²U/dx² < 0 U = maximum Unstable equilibrium.

hey can u help me i dont know hindi 1. what is the answer to this sum 28.35 2. what is that in 36.54

[@kupammakesavalu3491]

@Yoey here point B has more potential energy compared to point E which means it is unstable but when sir compared point B and A , B is stable so due to this problem we should use the concept of local maxima or minima which means comparing only nearby or surrounding points

[@kupammakesavalu3491]

@@yoey1097 sir is saying understand how it is moving( in that red line ) it is in unstable equilibrium with respect to x axis if u give a little push the ball or the particle start moving but with respect to y axis particle is in stable equilibrium so if u give a small push the particle will come back towards its position 😇 hope u understood if u didnt understand u can just imagine a vertical line and a horizontal line where vertical line is y axis and horizontal is x axis and imagine the movement of the particle

@Aditya Eswar sorry bro I can only understand it I know tamil

yes we are lucky to have nice teacher like him

Q3: x= +2,-2 At x=+2 U is minimum i.e stable. At U =-2 U is maximum i.e unstable

[@VanDana-p3l]

Answer questions is two value +2 and -2 is put in dowel derivation is value -40 is minimum is stable equilibrium 🎉🎉🎉

Richard Feynman ko jaanta hoon sir. He's one of my favorite physicists. I have seen some of his interviews, and in them I could really feel what a visionary the man is. I'm delighted that you brought his name up.

Thank you sir it made my concept up to mark for comeptition

wah nice

Homework answer Pos of eq. 2m/-2m At 2m stable eq. Ar -2m unstable eq.

[@Vaishali-q3x]

My inspiration u only sir becoz i love teaching phy and che I will help others like u sir

[@prabhamishra1099]

Ans of ques.3:. x=2,-2 At x=2 Stable and at x=-2 Unstable equilibrium!!!!

[@mymanindia]

Prabha Mishra no you are wrong answer is this: At x=4(Stable) and at x=-4(Unstable)

[@bnaziroddin8532]

Dollar -prabha mishra is right!!

[@hardiksharma3060]

Dollar u r right

[@amanraj_0287]

How dollar lol just tell me ...

[@anshitgoel8161]

Yes

after 3 years still his videos ka rocking

[@nnn8277]

du/dx= o We get x= -2 & x = 2 dy2/dx2= 2x At x= -2 dy2/dx20 unstable

[@keepworkinghard8830]

kamal karte ho pandey sir behtareen explanation fata fat revision bhi

[@sohampatra1508]

Sir Pls make videos on centre of mass ..... And... Conservation of momentum..... Pls....... 🙂....... 🙂 ......... 🙂......... Pls......... 🙂

[@aniketdechalwal1226]

Sir ese hi kripya bnae rakhna bs ! Keep uploading ❤

[@akshatthakur4450]

haaa

[@KB_PracticalMind]

26:26 F=0 -du/dx =0 x²-4=0 x=+2 or -2 => At x = 2 and - 2, Equilibrium exists d²u/dx² = 2x At x = 2 => d²u/dx² = 4>0 => Stable equilibrium At x =-2 => d²u/dx² = -4 Unstable equilibrium

[@vivekpatel7452]

25:00 ans Equilibrium points are +2.& -2 And nature are stable &unstable equilibrium Thank you sir ☺️☺️
