Body of mass 2 kg rests on the horizontal plane. Calculate the normal – InterviewSolution

1.

Body of mass 2 kg rests on the horizontal plane. Calculate the normal force acting on the body.

Answer»

Answer:

The maximum static FRICTION, f

s,max

=μ

s

N=0.5×2kg×10ms

−2

or, f

s,max

=10N>2.5N, which is GREATER than the applied horizontal force.

Hence, friction can impede the motion and the NECESSARY required frictional force to balance the horizontal applied force will be equal.

Therefore, f=2.5N.
