Question

# For $$F_1= 150N$$ and $$F_2 = 100 N$$, find the direction and magnitude of friction force acting on the block.

A
90 N, making an angle of tan1(25) with the horizontal in the upward direction.
B
75 N, making an angle of tan1(25) with the horizontal in the upward direction.
C
107.7 N, making an angle of tan1(25) with the horizontal in the upward direction.
D
Zero.

Solution

## The correct option is B 75 N, making an angle of $$tan^{-1}\Big(\dfrac{2}{5}\Big)$$ with the horizontal in the upward direction.Physics
