means if angle changes work done will not b zero? if angle changes and still it returns to same point then will it b zero?

its clear now Thanks a globe :smile:

is not it the case similar to simple pendulum and time period for simple pendulum is T=2.pi sqrt(L/g) ?

when we start from a point say 'O' cover some distance and back to same point work done in the case is zero.will it be zero too for the non-central force as given below in pic.. am i solving it in the right way? :oldconfused:

Isn't it similar to Lagrange equation of motions?

Can anybody explain in simple and easy words "Lagrange Multiplier" What is it? and when it is used? i googled it but that was explained in much difficult words.

If car passes very very very quickly in front of you, you will not be able to see it... We will not be able to observe it... As seeing is believing, So which proof we have that this car really existed and passed in front of us?I Think the concept of electrostatic isn't it?

i will try this also Thank you :)

can't we use F=K[q1][q2]/r^2 ?
