A) \[\hat{k}\]
B) \[\hat{i}+\hat{j}\]
C) \[\frac{\hat{i}+\hat{j}}{\sqrt{2}}\]
D) \[\frac{\hat{i}+\hat{j}}{2}\]
Correct Answer: C
Solution :
\[\hat{R}\]\[=\frac{{\vec{R}}}{|R|}=\frac{\hat{i}+\hat{j}}{\sqrt{{{1}^{2}}+{{1}^{2}}}}=\frac{1}{\sqrt{2}}\hat{i}+\frac{1}{\sqrt{2}}\hat{j}\]You need to login to perform this action.
