The ratio of maximum and minimum magnitu...

The ratio of maximum and minimum magnitudes of the resultant of two vectors `vec(a)` and `vec(b)` is 3:1. Now, `|vec(a)|` is equal to

A

`P=2Q`

B

`P=Q`

C

`PQ= 1`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
According to problem `P+Q= 3` and `P-Q=1`
By solving we get `P=2` and `Q-1`
`:. P/Q= 2 implies P= 2Q`
