For the potential energy curve shown shown in figure.

(a) Find directions of force at points `A, B, C,D` and `E`.
(b) Find positions of stable, unstable and neutral equilibriums.

Text Solution

Verified by Experts

(a) `F = - (dU)/(dr)` or `-(dU)/(dx) = -("slope of U-x graph")`
(b) At point `x =2m`, potential energy is minimum So. It is stable equilibrium positions.
At `x = 2m`, potential energy is maximum. So, it is unstable equilibrium position. Tere is no point, where potential energy is constant. So, we don't have any point of unstable equilibrium position.
