Two vectors vec(A) and vec(B) inclined a...

Two vectors `vec(A) and vec(B)` inclined at an angle `theta` have a resultant `vec(R )` which makes an angle `alpha` with `vec(A)`. If the directions of `vec(A) and vec(B)` are interchanged, the resultant will have the same

A

direction

B

magnitude

C

direction as well as magnitude

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
Neither the magnitude of vectors nor the angle between the vectors is changed. So, magnitude of the resultant remains unchanged. However, the direction of the resultant will be changed.
