A) \[6\widehat{j}\,Nm\]
B) \[-6\,\widehat{i}\,Nm\]
C) \[6\,\widehat{k}\,Nm\]
D) \[6\,\widehat{i}\,Nm\]
Correct Answer: B
Solution :
| [b] |
| \[\overrightarrow{\tau }=\overrightarrow{r}\times \overrightarrow{F}\] |
| \[\overrightarrow{\tau }=2\,\overrightarrow{k}\times 3\,\overrightarrow{j}\] |
| \[\overrightarrow{\tau }=6\,\overrightarrow{i}\,\,Nm\] |
