The resultant of vecA and vecB makes an ...

The resultant of `vecA and vecB` makes an angle `alpha` with `vecA` and `beta and vecB`,

A

`alphaltbeta`

B

`alphaltbeta` if `AltB`

C

`alphaltbeta` if `AgtB`

D

`alphaltbeta` if `A=B`

Text Solution

Verified by Experts

The correct Answer is:
C

Resultant is inclined towards vector of large magnitude thus. If `A gt B` then `alpha lt beta`.
