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

A

x1is in stable equilibrium

B

x2 is in stable equilibrium

C

x3 is in stable equilibrium

D

None of these

Answer

None of these

Explanation

Solution

x = x1 and x = x3 are not equilibrium positions because ¹ 0 at these points. x = x2 is unstable, as U is maximum at this point.
