Questions  

A horizontal force F acts on the block of mass m and the block remains stationary, if we pull the block by the force F making an angle θ and the block remains stationary, the value of friction force is

 

 

a
μ mg
b
F cos θ
c
μmgsin θ+μ cos θ
d
μmg1+μ2

detailed solution

Correct option is

fs > F cos θ (Since block is stationary)f = F cos θ
