If `|veca|=4,|vecb|=2` and angle between `veca and vecb is pi/6 then (vecaxxvecb)^2` is (A) 48 (B) `(veca)^2` (C) 16 (D) 32

If |veca+vecb|^2=|veca|^2+|vecb|^2 then angle between veca and vecb is

If |vecA-vecB|=|vecA|=|vecB| , the angle between vecA and vecB is

If vecA*vecB=|vecAxxvecB| . Then angle between vecA and vecB is

If |veca.vecb|= |veca xx vecb| , then the angle between veca and vecb is

If veca is perpendicuar to vecb and vecc |veca|=2, |vecb|=3,|vecc|=4 and the angle between vecb and vecc is (2pi)/3, then [veca vecb vecc] is equal to (A) 4sqrt(3) (B) 6sqrt(3) (C) 12sqrt(3) (D) 18sqrt(3)

If |vecA+vecB|=|vecA|+|vecB| , then angle between vecA and vecB will be

If |veca - vecb|=|veca| =|vecb|=1 , then the angle between veca and vecb , is

If the angle between veca and vecb is (pi)/(3) , then angle between 2veca and -3vecb is :

If vecA.vecB = |vecA xx vecB| , find angle between vecA and vecB .

if| vecAxxvecB|=|vecA.vecB| , then angle between vecA and vecB will be
