(A) = mg
(B) > mg
(C) < mg
(D) either b or c depending upon acceleration of chain

In the figure ball A is released from rest, when the spring is at its naturallength. For the block B of mass M to leave contact with the ground atsome stage, the minimum mass of A must be
(A) 2M
(B) M
(C) M/2
(D) a function of M and force constant of spring.

(A) R
(B) R/3
(C) R / 2
(D) Body can’t start pure rolling for any value of ‘h’

A small ball starts rolling on an inclined track whichbecomes loop if radius R in vertical plane.
(A) Speed of the ball at highest point is zero but and highest point is 2R above the ground.
(B) Speed of the ball at highest point is non zero but highest point is 2R above the ground
(C) Speed of the ball is along horizontal at highest point and highest point is less than the 2R above the ground.
(D) Speed of the ball is along horizontal at highest point but height of highest point above the ground can not be calculated.

If the tension in a stretched string fixed at both ends in changed by 20%, the fundamental frequency is found to change by 15 Hz. Then the
