Question

An object of mass 10 g is sliding with a constant velocity of 2m/s on a frictionless horizontal table the force required to keep the object moving with the same velocity is _______( answer in full process)

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 B.
