Question

Ramu applied a force of 10 N on a body to move it from rest. He wants to express the applied force is in terms of the various system of the unit. Express 10 N force in terms of $gcm{s}^{-2}$.

• A. ${10}^{5}gcm{s}^{-2}$
• B. ${10}^{6}gcm{s}^{-2}$
• C. ${10}^{7}gcm{s}^{-2}$
• D. ${10}^{4}gcm{s}^{-2}$

Answer 1

The correct option is B ${10}^{6}gcm{s}^{-2}$

Force $=$ mass $\times$ acceleration

Thus, SI unit of force is $kg$ $m/s^2$ and it is also equal to newton (N).

So, $10N=10$ $kg$ $m/s^2=10\times \left(1000g\right)\left(100cm\right)/s^2={10}^6$ $g$ $cm$ $s^{-2}$
