The time taken by a particle performing SHM on a straight line to pass from point A to B where it's velocities are same is 2 seconds. After another 2 seconds it returns to B. The time period of oscillation is (in seconds):

For a particle in S.H.M., if the amplitude of displacement is ‘a’ and the amplitude of velocity is ‘v’ the amplitude of acceleration is :

A body performs SHM along the straight line segment  ABCDE with C as the mid point of segment AE (A and E are the extreme position for the SHM). Its kinetic energies at B and D are each one fourth of its maximum value. If length of segment AE is 2R, then the distance between B and D is : 

A system is shown in the figure. The time period for small oscillations of the two blocks will be :

Two light strings, each of length l, are fixed at points A and B on a fixed horizontal rod xy. A small bob is tied by both strings and in equilibrium, the strings are making angle 45° with the rod. If the bob is slightly displaced normal to the plane of the strings and released then period of the resulting small oscillation will be :

A metre stick swinging in vertical plane about a fixed horizontal axis passing through its one end undergoes small oscillation  of  frequency f₀ as shown in figure. If the bottom half of the stick were cut off, then its new  frequency of  small oscillation would become:

A 25 kg uniform solid sphere with a 20 cm radius is suspended by a vertical wire such that the point of suspension is vertically above the centre of the sphere. A torque of 0.10 N-m is required to rotate the sphere through an angle of 1.0 rad and then maintain the orientation. If the sphere is then released, its time period of the oscillation will be:

A rod of length l is in motion such that its ends A and B are moving along x-axis and y-axis respectively. It is given that  rad/s always. P is a fixed point on the rod as shown in figure. Let M be the projection of P on x-axis. For the time interval in which q changes from 0 to π/2 ,

Which of the following is greatest in SHM ? (assuming potential energy = 0 at mean position)

m₁ & m₂ are connected with a light inextensible string with m₁ lying on smooth table and m₂ hanging as shown in figure. m₁ is also connected to a light spring which is initially unstretched and the system is released from rest :
