A body of mass 2 kg suspended through a vertical spring executes simple harmonic motion of period 4s. If the oscillations are stopped and the body hangs in equilibrium, find the potential energy stored in the spring.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(40 J)
K = mꞷ 2
⇒ K = m 
K = 
mg = Kx equilibrium
x = 
⇒ U = 
Kx 2
= 
K 
= 
= 
= 40 J
