What is the maximum value of the force F such that the block shown in the arrangement, does not move?

A

20 N

B

10 N

C

12 N

D

15 N

Text Solution

Verified by Experts

The correct Answer is:
A

`f=muR=mu(W+Fsin60^(@))`
`Fcos60^(@)=mu(W+fsin60^(@))`
Substituting `mu=1/(2sqrt3)` and `W=10sqrt3`, we get F=20 N
