Force constant of a spring is 100 N//m. ...

Force constant of a spring is 100 `N//m`. If a 10kg block attached with the spring is at rest, then find extension in the spring.
`( g= 10 m//s^(2)`)

Text Solution

Verified by Experts

In this situation spring is in extended state so spring force acts in upward direction.
Let x be extension in the spring.
