Question: 26/60 A particle free to move along the x-axis has potential energy given by U(x) =k[1 exp (-x)]for o xSto, where k is a positive constant of appropriate dimensions. Then At points away from the origin, the particle is in unstable equilibrum For any finite non-zero value of x, there is a force directed away from the origin (A) (B) (C) f its total mechanical energy is k2, it has its minimum kinetic energy at the orign For small displacement from x = 0, the motion is simple harmonic (D)
