Question

A body of mass 4 kg experiences two forces $\overrightarrow{\mathrm{F}}_1=5 \hat{\imath}+8 \hat{\jmath}+7 \hat{\mathrm{k}}$ and $\overrightarrow{\mathrm{F}}_2=3 \hat{\imath}-4 \hat{\jmath}-3 \hat{\mathrm{k}}$. The acceleration acting on the body is :

Select the correct option:

$-2 \hat{\imath}-\hat{\jmath}-\hat{k}$

$4 \hat{\imath}+2 \hat{\jmath}+2 \hat{k}$

$2 \hat{\imath}+\hat{\jmath}+\hat{k}$

$2 \hat{\imath}+3 \hat{\jmath}+3 \hat{k}$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

$\begin{aligned} & \text { Net force }=8 \hat{\imath}+4 \hat{\jmath}+4 \hat{k} \\ & \vec{a}=\frac{\vec{F}}{m}=2 \hat{\imath}+\hat{\jmath}+\hat{k}\end{aligned}$
