A block of weight `9.8N` is placed on a table. The table surface exerts an upward force of `10N` on the block. Assume `g=9.8m//s^(2)`.

A

The block exerts a force of `10N` on the table

B

The block exerts a force of `19.8N` on the table

C

The block exerts a force of `9.8N` on the table

D

The block has an upward acceleration.

Text Solution

Verified by Experts

The correct Answer is:
A, D
From Newtons third law, the force exerted by table on block is equal to that exerted by block on the table. Therefore block exerts a `10N` force on table. Since the upward force on the block is larger than downward force, it moves upwards.
