Question

5. An object of mass 2 kg is sliding with a constant
velocity of 4 ms-1 on a frictionless horizontal table. The
force required to keep the object moving with the same
velocity is
(a) 32 N
(b) ON
(c)2N
(d) 8N
6. Rocket works on the principle of conservation of
(a) mass
(b) energy
(c) momentum
(d) velocity​

Answer 1

Answer:

hope it helps

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.
