A) \[yz-\]plane
B) \[z-\]axis
C) \[y-\]axis
D) \[x-\]axis
E) \[xz-\]plane
Correct Answer: D
Solution :
\[\overrightarrow{L}=\overrightarrow{r}\times \overrightarrow{P}=\left| \begin{matrix} {\hat{i}} & {\hat{j}} & {\hat{k}} \\ 1 & 2 & -1 \\ 3 & 4 & -2 \\ \end{matrix} \right|\] \[\overrightarrow{L}=\hat{i}(-4+4)-\hat{j}(-2+3)+\hat{k}(4-6)\] \[=-\hat{j}-2\hat{k}\] \[\overrightarrow{L}\]has components along -y axis and\[-z\]axis. The angular momentum is in y-z plane ie, perpendicular to\[x-\]axisYou need to login to perform this action.
