Question

A block of mass 2Kg is sliding on a frictionless horizontal plane surface with a speed 4m/s. Find

the magnitude of required unbalanced force to maintain the same speed in the body.​

Answer 1

Explanation:

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.

Answer 2

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.
