Question

if a body of mass 20 kg is placed on a rough surface . when a force of 5N is applied in east direction, the body remains at the same position the value of frictional force _ and _direction​

Answer 1

If the body remains at the same position that means the friction force is equal to the applied force or maybe greater.

So the frictional force is 5N in opposite direction I.e west....

Answer 2

Answer:

frictional force:5N&direction:west

Explanation:

m=20kg

P=5N

fs=applied force

So,fs=5N

Direction=East but friction is act as opposite direction.So,then direction is west.
