An object of mass 5 kg is sliding with a constant velocity of 4 m s¯¹ on a frictionless horizontal surface. The force required to keep the object moving with the same velocity is
Since the object is moving with a constant velocity on a frictionless surface, there’s no net force acting on it! According to Newton’s first law, an object in motion stays in motion with the same velocity unless acted upon by an external force.
So, the force required to keep it moving with the same velocity is:(b) 0 N

(b) As the object is moving on a frictionless horizontal surface with a constant velocity of 4 m s¯¹, its acceleration is zero and hence no force is acting on the given object.
