A block of mass 0.1 is held against a wall applying a horizontal force of 5N on block. If the coefficient of friction between the block and the wall is 0.5, the magnitude of the frictional force acting on the block is:

A

2.5 N

B

0.98 N

C

4.9N

D

0.49N

Text Solution

Verified by Experts

The correct Answer is:
B
The magnitude of the frictional forcef has to balance the weight 0.98 N acting downwards.
Therefore the frictional force =0.98N
