SHMHard
Question
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/sec2)
(g = 10 m/sec2)
Options
A.
s
s B.
s
s C.
s
s D.
s
sSolution
acceleration a = ω2x
maxm acceleration amax = ω2A =
When block and platform are separated
amax = g = 10
= 10 ⇒ T2 = 
T = π/10sec
maxm acceleration amax = ω2A =
When block and platform are separated
amax = g = 10
= 10 ⇒ T2 = T = π/10secCreate a free account to view solution
