A force \(\vec{F} = (5\hat{i} + 3\hat{j}) \text{ N}\) is applied over a particle which displaces it from its original position to the point \vec{s} = (2\hat{i} - \hat{j}) m. The work done on the particle is
Text Solution
Verified by ExpertsThe correct answer is:
B
\(\mathbf{W} = \vec{\mathbf{F}} \cdot \vec{\mathbf{s}} = (5\hat{i} + 3\hat{j}) \cdot (2\hat{i} - \hat{j}) = 10 - 3\) = 7J
