Q7 The effective potential energy diagram Veff Versus r for a particle moving under a central force is shown in the figure. Total energy of the particle is U. The initial angular momentum of the particle is L having a non zero value. a. The kinetic energy of the particle is zero at r = r1 b. The effective potential energy is equal to U at r =r1 C. The particle retraces its path after it reaches r = r d. The radial velocity of the particle is zero atr=ri e. The motion of the particle is unbound.
