Vedclass · Answer

(B) According to Newton's First Law of Motion,an object in motion will continue to move with a constant velocity in a straight line unless acted upon by an external unbalanced force.Since the body is moving with a constant velocity of $4 \, m/s$ on a frictionless surface,there is no acceleration $(a = 0)$.Using Newton's Second Law,$F = ma$.Substituting the values,$F = 2 \, kg 	imes 0 \, m/s^2 = 0 \, N$.Therefore,no external force is required to maintain the constant velocity.

$A$ body of mass $2 \, kg$ is sliding with a constant velocity of $4 \, m/s$ on a frictionless horizontal table. The force required to keep the body moving with the same velocity is .......... $N$.
