A rectangular box lies on a rough inclined surface. The coefficient of friction between the surface and the box is `(mu)` Let the mass of the box be m.
At what angle of inclination `theta` of the plane to the horizontal will the box just start to slide down the plane ?

Text Solution

Verified by Experts

The correct Answer is:
When the box just starts sliding
`mu= tan theta`
`or theta=tan^(-1) mu`
