If `|veca|=2,|vecb|=7 and (vecaxxvecb)=3hati+2hatj+6hatk` find the angle between `veca and vecb`

If veca and vecb asre two vectors such that |veca|=2, |vecb| = 7 and vecaxxvecb=3hati+6hatk find the angle between veca and vecb

If veca+3vecb=3hati-hatj and 2veca+vecb=hati-2hatj ,then what is the angle between veca and vecb ?

If veca=2hati+3hatj+6hatk and vecb=6hati+3hatj-2hatk , find the angle, between vectors veca and vecb . Also find unit vector perpendicular to both veca and vecb

If a=4hati+2hatj-hatk and vecb=5hati+2hatj-3hatk find the angle between the vectors veca+vecb and veca-vecb

If vecA=2hati+hatj-hatk. vecB=hati+2hatj+3hatk and vecC=6hati-2hatj-6hatk then the angle between (vecA+vecB) and vecC will be :-

vecA=4hati+4hatj-4hatk and vecB=3hati+hatj+4hatk , then angle between vectors vecA and vecB is

If vecA = hati + 2hatj - hatk , vecB = - hati + hatj - 2hatk , then angle between vecA and vecB is

The magnitude of two vectors vecA and vecB is 3 and 4 respectively . If vecAxxvecB=5hati+6 hatj-7hatk . Calculate the angle between vecA and vecB .

If veca=hati+hatj+hatk, veca.vecb=1 and vecaxxvecb=hatj-hatk then vecb

If vecA= 2hati-2hatj-hatk and vecB= hati+hatj , then : (a) Find angle between vecA and vecB . (b) Find the projection of resultant vector of vecA and vecB on x-axis.
