A) \[5\sqrt{2}\]
B) \[5\sqrt{3}\]
C) 5
D) 2.5
Correct Answer: B
Solution :
With reference to figure line OB is perpendicular to the plane. So the component of \[\vec{A}\]along OB is \[10\cos {{30}^{o}}\]i.e., \[5\sqrt{3}.\] Hence, the correction option is (b).You need to login to perform this action.
