Question

____ is the force when acting on the body of mass _____ produces an acceleration of $1m{s}^{-2}$.

• A. $1N$
• B. $1kg$

Answer 1

1. As per Newton's second law $F=ma$
2. The unit of force is $kgm{s}^{-2}orN$.

Hence $1N$ is the force when acting on the body of mass $1kg$ produces an acceleration of $1m{s}^{-2}$.
