What is the angle between `vecA` and the resultant of `(vecA+vecB)` and `(vecA-vecB)` ?

A

`0^(@)`

B

`tan^(-1)((A)/(B))`

C

`tan^(-1)((B)/(A))`

D

`tan^(-1)((A-B)/(A+B))`

Text Solution

Verified by Experts

The correct Answer is:
1
`vecR = (vecA+hatB) + (vecA-hatB) rArr vecR= 2vecA`
Thus `vecR and vecA` are in same direction.
