A block of mass m is pressed against a spring and released, as shown in the figure. What is the minimum compression in spring for which normal reaction of the block and velocity of the block, simultaneously, become zero in subsequent motion on loop?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Velocity becomes zero when height attained by block is maximum, and the spring force is stored as potential energy.
