a body is in limiting equilibrium on a rough inclined plane at angle of 30degree with horizontal. calculate the acceleration with which the body will slide down when inclination of the plane is changed to 60degree.?
1 Answer
In first case when the body is in limiting equilibrium at angle of inclination of the inclined plane,
then the downward force along the inclined plane is just balanced by the frictional force ,. So we have
where
In the second case when the angle of inclination is
So acceleration of the body
