A block of mass 2kg is kept on the floor...

A block of mass `2kg` is kept on the floor. The coefficient of static friction is `0.4` . If a force `F` of `2.5N` is applied on the block as shown in the figure, the frictional force between the block and the floor will be.

A

`2.5N`

B

`5N`

C

`7.84N`

D

`10N`

Text Solution

Verified by Experts

The correct Answer is:
A

Appiled force `=2.5N`
Limiting friction `=mumg=0.4xx2xx9.8=7.84N`
For the given condition applied force is very smaller than limiting friction.
:. Static friction on a body=Applied force
`=2.5N`
