Find the angle between two vectorsoverse...

Find the angle between two vectors`oversetrarra"and"oversetrarrb` with magnitudes `sqrt3"and"2` respectively having`oversetrarra.oversetrarrb=sqrt6`.

Text Solution

Verified by Experts

`cos theta =(veca.vecb)/(|veca|.|vecb|)`
`sqrt6/(sqrt3xx2)=sqrt2/2 =1/sqrt2`
` implies theta=pi/4`
