Theree coplanar vectors `vecA,vecB` and `vecC` have magnitudes 4.3 and 2 respectively. If the angle between any two vectors is `120^(@)` then which of the following vector may be equal to `(3vecA)/(4)+(vecB)/(3)+(vecC)/(2)`

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
As `|vec(B)/3|=|vec(C)/2|` so `vec(B)/3+vec(C)/2=-vec(A)/4` therefore `(3vec(A))/4+vec(B)/3+vec(C)/2=vec(A)/2`
