A block of mass 0.1 kg is held against a wall applying a horizontal force of 5 N on the 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

`4.9 N`

D

`0.49 N`

Text Solution

Verified by Experts

The correct Answer is:
b
The magnitude of the frictional force `f ` has to balan weight `0.98N` acting downward
`f_(1) = 0.3 xx 5 = 2.5 N`
`f lt f_(1)`

Therefore the frictional force is `0.98N` Hence option(b) is is the correct option
