Question

A block of mass 10 kg is on a rough horizontal surface. A horizontal force of a 4 N is applied on it. If the co-efficient of static friction between those two surfaces is 0.5, frictional force between the two surface in contact is

$\boxed{HERE\:IS\:YOUR\:ANSWER}$

$\mathcal{\green{ANSWER:}}$

4N as the force applied is less than maximum frictional force

( i.e. 10kg × 10m/s^2 × 0.5 = 50 N) .

$<u><b>therefore:</u></b>$

frictional force is equal to the the force applied
