A block of mass m is resting on a piston as shown in figure which is moving vertically with a SHM of period 1 s. The minimum amplitude of motion at which the block and piston separate is:
Text Solution
Verified by ExpertsThe correct answer is:
A
Acceleration = ꞷ 2 x
⇒ a max = 
A
When a max = g
then block and piston will be separated
a max = g = 
A ; (g = π 2 )
g = 
A
⇒ A = 
= 0.25 m
