A small block of mass m is placed at a distance r from one end of a plank. The plank is given a constant angular velocity `omega` about an axis passing through point O and perpendicular to the plane. The block starts sliding down the plane when the plank makes an angle `theta` with horizontal. Calculate the coefficient of friction between the particle and the plank.

Text Solution

Verified by Experts

The correct Answer is:
`g tan theta-(r^(2)omega)/(g cos theta)`

A box of mass 4 kg is placed on a wooden plank of length 1.5 m which is lying on the ground. The plank is lifted from one end along its length so that it becomes inclined. It is noted that when the vertical height of the top end of the plank from the ground becomes 0.5 m, the box begins to slide. Find the coefficient of friction between the box and the plank.
