InterviewSolution

1.	If the magnitude of two vectors are 3 and 4 and their scalar product is 6, find angle between them and also find \|vecA xx vecB\|.
Answer» SOLUTION :`vecA. vecB=AB cos THETA,\|vecA XX vecB\|=AB SIN theta` or `6 = (3xx4)cos theta"" = 3xx4 xx sin 60^(@)` `or theta =60^(@)"" =3xx4xx(SQRT(3))/(2)=6sqrt(3)`
