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

magnitude the same

B

direction reverses and megnitude is doubled

C

magnitude as well as direction

D

Neither

Text Solution

Verified by Experts
