Force acting on a particle constrained t...

Force acting on a particle constrained to move along x-axis is `F=(x-4)`. Here, F is in newton and x in metre. Find the equilibrium position and state whether it is stable or unstable equilibrium.

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
`F=(x-4)`
`F=0` at `x=4m`
When `xgt4m, F = +ve`
When displaced from `x=4m` (towards positive direction) force also acts in the same direction.

Therefpre, equilibrium is unstable.
