Question 1
Three S.H.M. of equal amplitude A and equal time period in the same direction combine. The difference in phase between each pair is 60 ° ahead of the other. The amplitude of the resultant oscillation is –
Question 2
For a particle executing simple harmonic motion, the correct variation of acceleration a with displacement x is given by
Question 3
A mass M is suspended from a spring of negligible mass. The spring is pulled is a little and then released so that the mass executes simple harmonic oscillations with a time-period T. If the mass is increased by m, then the time period becomes . The ratio of (m/M) is -
Question 4
A spring mass system is hanging from the ceiling of an elevator in equilibrium. The elevator suddenly starts accelerating upwards with acceleration a, the amplitude of the resulting S.H.M. is -
Question 5
Two S.H.M’s of unequal amplitude with same frequency (act) on a particle at right angles, with a phase difference of π/2. The resultant motion is –
Question 6
A solid sphere (M) attached to a massless spring (K) can roll without slipping along a horizontal surface. If the system is released after an initial stretch, the time period will be–
Question 7
The pendulum of the grandfather’s clock takes 1 sec to oscillate from one end to another a distance of 10 cms. Considering it a simple pendulum, find its maximum velocity-
