A particle of mass m is constrained to move on x-axis. A force 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 acting on the particle. The particle is displaced a distance A towards left from the equilibrium position E and released from rest at t = 0. Take point E at x = 0.Find minimum time it will take to reach from x = - A/2 to 0.(A) 3/2√(mA/F)(√2 - 1)(B) √(mA/F)(√2 -1)(C) 2√(mA/F)(√2 - 1)(D) none |
