The total energy of a body performing S.H.M. depends on

A particle of mass m oscillates with simple harmonic motion between points x₁ and x₂ the equilibrium position being O.  Its potential energy is plotted.  It will be as given below in the graph

A simple pendulum is executing simple harmonic motion with a time period T.  If the length of the pendulum is increased by 21%, the increase in the time period is

A particle is executing S.H.M of amplitude 4 cm and T = 4 sec.  The time taken by it to move from positive extreme position to half the amplitude is

A particle is subjected to two mutually perpendicular simple harmonic motions such that is x and y coordinates are given by


The path of the particle will be

A horizontal surface moves up and down in S.H.M with an amplitude of 1 cm.  If mass of 10 kg (which is placed on the surface) is to remain continuously in contact with it, the maximum frequency of S.H.M. will be

A particle is performing simple harmonic motion along x axis with amplitude 4 cm and time period 1.2 sec.  The minimum time taken by the particle to move from x = + 2 cm to x = + 4 cm and back again is
