A) 100 J
B) 150 J
C) 120 J
D) 200 J
E) 50 J
Correct Answer: B
Solution :
Force \[\overrightarrow{F}=(2\hat{i}+15\hat{j}+6\hat{k})N\] Displacement \[\overrightarrow{s}=10\hat{j}\,m\] Work done \[W=\overrightarrow{F}\cdot \overrightarrow{s}\] \[=(2\hat{i}+15\hat{j}+6\hat{k})\cdot (10\hat{j})\] \[=150\,J\]You need to login to perform this action.
