Question

An object of mass 15 kg is sliding with a constant velocity of 10 ms¹ on a frictionless horizontal table. The force required to keep the object moving with the same velocity is (a) 150 N (c) 0 N (b) 15 N (d) 10 N​

Answer 1

Answer:

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 . hence answer is 0
