Question

A wooden block of weight 200 N is placed on a table. The force exerted by the surface of the table on the block will be.......

Answer 1

Answer:

here the case is

about Newton's 3rd law of motion

Explanation:

that is "every action has equal and opposite reaction" so, here the wooden block is exerting a force of 200 N so the force exerted by the surface of the table on the block will also 200 N

Answer 2

Given:

Weight of wooden block = 200 N

To Find: Force exerted by the surface of the table on the block

Calculation:

• Weight is defined as the force with which a body is pulled towards the centre of earth.
• Weight is the force of gravity acting on any body.
• Weight is expressed in Newtons.
• From third law of motion, every force of action will have an equal and opposite force of reaction.
• A block kept on table, exerts a force of 200 Newtons on the table due to force of gravitation.
• So, to balance that force and not let the block fall on ground, an equal in magnitude but opposite in direction force is exerted by the table on the block.
• The force exerted by the table on block is 200 Newton in upward direction.

Answer:

The force exerted by the surface of the table on the block will be 200 Newton in upward direction.
