Question

• A block is placed on the horizontal
surface. There are two forces acting
on the block. One, the downward pull
of gravity and other a normal force
acting on it. Are these forces equal and
opposite? Do they form action
reaction pair? Discuss with your
friends.​

Answer 1

Answer:

Explanation:No. The gravitational pull by the earth on the object and the gravitational pull by the object on the earth form the third law pair. The normal force on the object by the earth and the normal force by the object on the earth forms the third law pair. You can easily see this by looking at their FBD. Magnitude wise, they are equal but do not form action-reaction pair.
