A man pulls a block heavier than himself...

A man pulls a block heavier than himself with a lioght rope. The coefficient if friction is the same between the man and the ground, and between the block and the ground.

A

The block will not move unless the man also moves

B

The man can move even when the block is stationary

C

If both move, the acceleration of the man is greater than the acceleration of the block

D

None of the above assertions is correct

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
Let T = tension in the rope. Force T acts on both. The limiting force of friction is larger for the block than for the man. Each body will move when T exceeds the force of friction.
