A block of mass m is placed on a smooth wedge of inclination theta.The whole system is accelerated horizontally so that the block does not slip on the wedge. The force exerted by the wedge on the block has a magnitude.
Answers
For intermediate student answer is -mg sin theta
For lower standard answer will be just 'mg' because u are not taken to depth.
'Mg' is the force exerted by weight of the body which is equal to the force applied by inclined plane
As the body is at rest the force exerted by the inclined plain must be equal and opposite to the vertical component of gravitational force
The force exerted by the wedge <= the force exerted by the block on the wedge.
Explanation:
As per the question, the block is at rest. Therefore the force exerted by the block on the wedge should be greater than or equal to the force exerted by the wedge. For example, place a box or anyother block like substance against the wall and place your hand on it and try to push it as the force exerted by you increases the block comes to rest or if your force is insuffecient it falls down.
