Question

What is the net force acting on an object of mass $10kg$ moving with a uniform velocity of $10m{s}^{-1}$?

• A. $15N$
• B. $10N$
• C. $98N$
• D. $0N$

Answer 1

The correct option is D

$0N$

Since, body is having uniform velocity, hence, change in velocity is zero. Therefore, rate of change of velocity, i.e., acceleration is zero. As we know,
$F=\text{mass of body}\times \text{acceleration of body}$ by Newton's second law of motion. Therefore, force is zero.
