a force F=(6i-8j+10k)N produces accelaration of 1m/s^2 in a body. Calculate mass of the body.

Mass of the body is:

 a=\frac{\left | F \right |}{M}= \overrightarrow{F}= 6\hat{i}-8\hat{j}+10\hat{k}

\left | \overrightarrow{F} \right |= \sqrt{(6)^2+(8)^2+(10)^2}= \sqrt{200}

M=\frac{\left | \overrightarrow{F} \right |}{a}= \frac{\sqrt{200}}{1}= 10\sqrt{2}kg
