Question

A block of mass m is placed on a smooth horizontal surface as shown. The weight (mg) of the block and normal reaction (N) exerted by the surface on the block

• A. Form action - reaction pair
• B. Balance each other
• C. Act in same direction
• D. Both (a) and (b)

Answer 1

The correct option is B Balance each other

mg and N cannot form action - reaction pair as they are acting on same body.
They balance each other to keep the block at rest.
