A uniform force of $\displaystyle (3 \hat{i}+\hat{j})$ newton acts on a particle of mass $\displaystyle 2$ kg. Hence the particle is displaced from position $\displaystyle (2 \hat{i}+\hat{k})$ meter to position $\displaystyle (4 \hat{i}+3 \hat{j}-\hat{k})$ meter. The work done by the force on the particle is :
Official answer
(1)
$\displaystyle 9$ J
