Light ray incident along a vector $\displaystyle \overrightarrow{A O}(\overrightarrow{A O}=2 \hat{i}-3 \hat{j})$ emerges out along vector $\displaystyle \overrightarrow{O B}(\overrightarrow{O B}=C \hat{i}-4 \hat{j})$ as shown in the figure below. The value of $\displaystyle C$ is $\displaystyle \_\_\_\_$.
Official answer
From NTA’s final answer key for this paper.
