U is the PE of an oscillating particle and F is the force acting on it at a given instant . Which of the following is true ?

A

`(U)/(F) + x = 0`

B

`(2U)/(F) + x = 0`

C

`(F)/(U) + x = 0`

D

`(F)/(2U) + x = 0`

Text Solution

Verified by Experts

The correct Answer is:
B
The potential energy, `U = (1)/(2)kx^(2)`
`2U = kx^(2)=-Fx" "[because F =-kx]`
or `(2U)/(F)=-x or (2U)/(F)+x = 0`
