Question

17 :
If a horizantal pushing force of 45 N, just cause sliding of body of weight 100 N placed on the horizontal
surface, then the coefficient of friction between the body and the horizontal surface will be equal to
O 0.45
0.65
O 0.25
O 0.55​

Answer 1

Explanation:

if the force is just sufficient to slide means limiting of static friction is equal to the applied force.

F = u x N

where u = coefficient of friction

F = u x 100

45 = u x 100

u = 0.45
