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

(a) 32 N (b) 0 N (c) 2 (d) 8 N

As the object is not experiencing any damping force (like friction etc.) there is no need to apply an external force to keep it moving with the same velocity of 4 m/s.

So, F = 0 N.
