A body of mass $4 kg$ experiences two forces ${\vec{F}}_{1} = 5 \hat{i} + 8 \hat{j} + 7 \hat{k}$ and ${\vec{F}}_{2} = 3 \hat{i} - 4 \hat{j} - 3 \hat{k .}$ The acceleration acting on the body is:

Options:

Answer:

Solution:

Net force $\vec{F} = {\vec{F}}_{1} + {\vec{F}}_{2} = 8 \hat{i} + 4 \hat{j} + 4 \hat{k}$

Therefore, required acceleration $\vec{a} = \frac{\vec{F}}{m} = 2 \hat{i} + \hat{j} + \hat{k}$
