Question

A force applied on a mass as $\overrightarrow{F}=6\hat{i}-8\hat{j}+10\hat{k}$ N and the mass accelerates with $1m/s^2$ . What will be the mass of the body ?

• A. $10\sqrt{2}kg$
• B. $2\sqrt{1}0kg$
• C. $10kg$
• D. $20kg$

Answer 1

The correct option is A $10\sqrt{2}kg$

$Mass=\frac{|\overrightarrow{F}|}{a}=\frac{\sqrt{36+64+100}}{1}=10\sqrt{2}kg$
