As shown in figure a horizontal platform with a mass m placed on it is executing SHM along y-axis. If the amplitude of oscillation is 2.5 cm, the minimum period of the motion for the mass not to be detached from the platform is: (g = 10 m/sec 2 = π 2 )
A

Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(b, d)
acceleration a = ꞷ 2 x
maximum acceleration a max = ꞷ 2 A = 
When block and platform are separated
a max = g = 10
. 
= 10
⇒ T 2 = 
T = π /10sec
