A body is placed on an inclined plane and has to be pushed down. The angle made by the normal reaction with the vertical will be:-

A box is placed on an inclined plane and has to be pushed down. The angle of inclination

A box is placed on an inclined plane and has to be pushed down.The angle of inclination is

A box is placed on an inclined plane and has to be pushed down.The angle of inclination is

A box is placed on an inlcined plane and has to be pushed down. The angle of inlcination is

A body is sliding down an inclined plane having coefficient of friction 1//3 . If the normal reaction is three times that of the resultant downward force along the inclined plane, the angle between the inclined plane and the horizontal is

A body is sliding down an inclined plane having coefficient of friction 0.5. If the normal reaction is twice that of the resultant downward force along the inclined plane , then find the angle between the inclined plane and the horizontal.
