A) \[\frac{5}{\sqrt{2}}\]
B) \[\frac{3}{\sqrt{2}}\]
C) \[\frac{7}{\sqrt{2}}\]
D) \[\frac{1}{\sqrt{2}}\]
Correct Answer: A
Solution :
Magnitude of component of \[\text{\vec{A}}\]along \[\text{\vec{B}}\]\[\text{\vec{B}=}\frac{\vec{A}.\vec{B}}{|\vec{B}|}\] \[=\frac{(2i+3\hat{j}).(\hat{i}+\hat{j})}{\sqrt{2}}\] \[=\frac{2+3}{\sqrt{2}}=\frac{5}{\sqrt{2}}\]You need to login to perform this action.
