If the magnitude of two vectors are 3 and 4 and their scalar product is 6, find angle between them and also find `|vecAxxvecB|`.

Text Solution

Verified by Experts

`vecA.vecB=ABcostheta`
`|vecAxxvecB|=ABsintheta`
or `6=(3xx4)costheta`
`=3xx4xxsin60^(@)` or
`theta=60^(@)`
`=3xx4xx(sqrt3)/(2)=6sqrt3`
