The time taken by a particle executing simple harmonic motion of period ‘T’ to move from the mean position to half the maximum displacement is

A particle starts oscillating simple harmonically from its equilibrium position. Then the ratio of kinetic and potential energy of the particle at time T / 12 is ( T – time period)

The length of the seconds pendulum is 1 m on earth. If the mass and diameter of any planet is 1.5 times that of the earth, the length of the seconds pendulum on that planet will be nearly
