A 10 kg Aluminium block is dragged on a plain horizontal surface at a constant velocity of 2 m/s. A frictional force of 60 N acts on it. What is the net force acting on the block? Correct Answer 0 N

Concept:

According to Newton's 2nd Law of motion, "The net force on the body is equal to the product of mass and acceleration of the body."

Fnet = ma

where Fnet = Net force acting on object, m = mass of object, a = acceleration of object

Calculation:

Given:

m = 10 kg, Frictional force = 60 N, velocity of block (v) = 2 m/s ( constant )

since the velocity of the block is constant hence acceleration will be Zero.

∵ a = 0

hence, Fnet = m × 0

Fnet = 0 N
