2. Hook's law of spring states that if you stretch a spring from its equilibrium length by a displacement x, then the force F that the spring exerts on you is F = -c . Now a particle of mass m is executing oscillation obeying Hook's law. If the amplitude of oscillation is A, then its period is
(A)proportional to61f20042929b6.jpg
(B) independent of A
(C) proportional to 1/61f20042929b6.jpg
