Question 98

A box rests on a rough plane inclined at 30∘ 30^\circ\,30∘ to the horizontal. The coefficient of friction between the box and the plane is 29\displaystyle \frac2992​. A horizontal force of magnitude 24 N acts towards the upper end of the plane. The box is on the point of slipping down the plane. Take g=9.8g=9.8g=9.8 m s−2^{-2}−2.
