A) \[4\times 6\]
B) \[6\times 3\]
C) \[5\times 6\]
D) \[4\times 3\]
Correct Answer: D
Solution :
Force \[\overrightarrow{F}=4\hat{i}+5\hat{k}\] Displacement \[\overrightarrow{s}=3\hat{i}+6\hat{k}\] Work done is given by \[W=\overrightarrow{F}\times \overrightarrow{s}=(4i+5j).(3i+6k)\] \[=4\times 3\]You need to login to perform this action.
