Question

An object of mass 2 kg is sliding with a constant velocity of 4 ms -1 on a frictionless horizontal table. The force required to keep the object moving with same velocity is

(a) 2 N
(b) 8 N
(c) 32 N
(d) 0 N​

Answer 1

From newton's Ist law of motion, since there is no external force acting on the object it will remain in its original state of motion. Hence, zero force is required to keep the object moving with constant velocity, correct answer is (d).
