A) \[\frac{5}{\sqrt{2}}\]
B) \[4\sqrt{2}\]
C) \[\frac{\sqrt{2}}{3}\]
D) None of these
Correct Answer: A
Solution :
[a] Component of \[\vec{A}\] along \[\vec{B}\,\,=\,A\,\cos \,\theta =\,\frac{\vec{A}.\vec{B}}{B}\] \[=\frac{2+3}{\sqrt{1+1}}\,=\frac{5}{\sqrt{2}}\]You need to login to perform this action.
