A body, constrained to move in the Y-direction is subjected to a force given by \(\vec{F} = (-2\hat{i} + 15\hat{j} + 6\hat{k}) \mathrm{N}.\) What is the work done by this force in moving the body a distance 10 m along the Y-axis
Text Solution
Verified by ExpertsThe correct answer is:
B
Force \(\vec{F} = (-2\hat{i} + 15\hat{j} + 6\hat{k}) \mathrm{N}\) and distance (d) = 10^{j} m .
Work done, \(W = \vec{F} \cdot \vec{d}\)
\(= (-2\hat{i} + 15\hat{j} + 6\hat{k}) \cdot (10\hat{j})\)
\(= 150 \, \mathrm{N} \cdot \mathrm{m} = 150 \, \mathrm{J}.\)
