A particle of mass m is constrained to move on x-axis. A fore F acts on the particle. F always points toward the position labeled E. For example, when the particle is to the left of E, F points to the right. The magnitude of F is a constant F except at point E where it is zero The system is horizontal. F is the net force acing on the particle. The particle is displaced a  distance A towards left from the equilibrium position E and released from rest at t = 0.What is the period of the motion?Velocity–time graph of the particle is
