Figure showns three vectors p,q and r where C is the mid - point of AB Then which of the following reation is correct ?

A

`p+q=2r`

B

`p+q=r`

C

`p-q=2r`

D

`p-q=r`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) from the figure OB+BC=r or q+BC=r`
OA+AC=r
or P+AC=r`
Adding these two equations we gt `P+q=2r,as AC asnd`BC are equal and opposte vectors.
