Q.

A body of mass 4 kg lying on a rough plane inclined at \(30^\circ\)  to the horizontal has an acceleration of 2 ms\(^{-2}\)  when pulled directly up the plane by a force of 6 kg wt. Calculate its acceleration when a force of 6 kg wt. Calculate its acceleration when a force of 3 kg wt is applied down the plane. Given : g = 10 ms\(^{-2}\).
