Q1. A particle is placed in a region with potential V(x) = 1/2kx2 - (λ)/(3)x3 where k, λ > 0, then
- (1) x = 0 and x = (k)/(λ) are points of stable equilibrium.
- (2) x = 0 is a point of stable equilibrium and x = k/λ is a point of unstable equilibrium.
- (3) x = 0 and x = k/λ are points of unstable equilibrium.
- (4) There are no points of stable or unstable equilibrium.
