In the figure shown the potential energy U of a particle is plotted its position 'x' from origin. Then which of the following statement is correct A particle at :

A

`x_(1)` is in stable equilibrium

B

`x_(2)` is in stable equilibrium

C

`x_(3)` is in stable equilibrium

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
D
`x = x_(1)` and `x = x_(3)` are not equilibrium positions because `(du)/(dx) ne 0` at these points
`x = x_(2)` is unstable, as U is maximum at this point.
