SHMHard
Question
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 :
Options
A.0.25 m
B.0.52 m
C.2.5 m
D.0.15 m
Solution
Acceleration (a) = ω2x ⇒ amax = 
When amax = g then block and piston will be separated
amax = g =
A ; (g = π2)
g =
A ⇒ A = 
= 0.25 m
When amax = g then block and piston will be separated
amax = g =
A ; (g = π2)g =
A ⇒ A = = 0.25 mCreate a free account to view solution
