A body of mass \(4 \mathrm{~kg}\) experiences two forces \(\overrightarrow{\mathrm{F}}_1=5 \hat{\mathrm{i}}+8 \hat{\mathrm{j}}+7 \hat{\mathrm{k}}\) and \(\overrightarrow{\mathrm{F}}_2=3 \hat{\mathrm{i}}-4 \hat{\mathrm{j}}-3 \hat{\mathrm{k}}\). The acceleration acting on the body is _______.
Pick an option to check your answer.
Answer & Solution
Correct Answer
(C) \(2 \hat{i}+\hat{j}+\hat{k}\)
Step-by-step Solution
Detailed explanation
\(\text { Net force }=8 \hat{i}+4 \hat{j}+4 \hat{k}\)
\(\vec{a}=\frac{\vec{F}}{m}=2 \hat{i}+\hat{j}+\hat{k}\)
