Answer:
0 N
Explanation:
To keep a body moving with same velocity, force mustn't be applied, because applying force means applying acceleration (F=mass*acceleration).
If acceleration is applied, it means velocity is not uniform.
Therefore, force to be applied to a body to keep the object moving with same velocity is 0 N.

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.
