Question

A light spring of stiffness k is hanging from the ceiling.it is stretched by a distance d then a mass m attached to the end A and then released.the magnitude of oscillation will be. Ans- mg/k-d Solution plz?

Answer 1

Hello dear,

● Answer-
mg/k - d

● Explanation-
Consider a spring with spring constant k stretched by d and then released.
Restoring force = Load - Force due to extension

Let, a = amplitude of oscillation, then
ka = mg - kd
a = mg/k - d

Amplitude of oscillation is mg/k-d .

Hope that is useful.
