If the mass of block is 1 kg and a force of 10 / `sqrt3` N is applied horizontally on the block as shown in the figure . The frictional force acting on the block is :

A

zero

B

`(10)/(sqrt3)`N

C

`(20)/(sqrt3) N`

D

5 N

Text Solution

Verified by Experts

The correct Answer is:
A

as F cos `30^(@)`=mg sin `30^(@) `
so f = 0
