The potential energy of a body is given ...

The potential energy of a body is given by `U = A - Bx^(2)` (where x is the displacement). The magnitude of force acting on the partical is

A

constant

B

Proportional to `x`

C

Proportional to `x^(2)`

D

Inversely proportional to `x`

Text Solution

Verified by Experts

The correct Answer is:
B
`U - A - Bx^(2) implies F = - (dU)/(dx) = 2 Bx implies F = x`
