A) \[-6\,\widehat{i}\,+6\widehat{j}-12\,\widehat{k}\]
B) \[-17\,\widehat{i}\,+6\widehat{j}-13\,\widehat{k}\]
C) \[6\,\widehat{i}\,+6\widehat{j}-12\,\widehat{k}\]
D) \[\widehat{i}\,-6\widehat{j}-5\,\widehat{k}\]
Correct Answer: D
Solution :
\[\tau =\overrightarrow{r}\times \overrightarrow{F}\] \[=\left| \begin{matrix} {\hat{i}} & {\hat{j}} & {\hat{k}} \\ 3 & -2 & 3 \\ 2 & -3 & 4 \\ \end{matrix} \right|\] \[=\hat{i}-6\hat{j}-5\hat{k}\]You need to login to perform this action.
