A force of `100N` need to be applied parallel to a smooth inclined plane just to hold a body on it. The angle of inclination of the inclined plane is plane is `30^(@)` . How much horizontal force need to be applied to do the same?

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. (a) At what angle of inclination 0 of the plane to the horizontal will the box just start to slide down the plane ? (b) What is the force acting on the box down the plane, if the angle of inclination of the plane is increased to a gt theta (c) What is the force needed to be applied upwards along the plane to make the box either remain stationary or just move up with uniform speed ? (d) What is the force needed to be applied upwards along the plane to make the box move up the plane with acceleration a ?
