If two vectors are `A = 2hati + hatj - hatk and B = hatj - 4hatk.` By calculation, prove AxxB isperpendicular to both A and B.

The two vectors A=2hati+hatj+3hatk and B=7hati-5hatj-3hatk are -

If two vectors are given as veca = hati - hatj + 2hatk and vecb = hati + 2hatj+hatk , the unit vector perpendicular to both vec a and vec b is

If two vectors are given as veca = hati - hatj + 2hatk and vecb = hati + 2hatj+hatk , the unit vector perpendicular to both vec a and vec b is

If the vectors a hati + 3 hatj - 2 hatk and 3 hati - 4 hatj + b hatk are collinear, then (a,b) =

Three vectors a=hati+hatj-hatk, b=-hati+2hatj+hatk and c=-hati+2hatj-hatk , then the unit vector perpendicular to both a+b and b+c is

Let a=3hati + 2hatj + 2hatk and b= hati + 2hatj - 2hatk be two vectors. If a vector perpendicular to both the a + b and a-b has the magnitude 12, then one such vector is:

Let a=3hati + 2hatj + 2hatk and b= hati + 2hatj - 2hatk be two vectors. If a vector perpendicular to both the a + b and a-b has the magnitude 12, then one such vector is:

A unit vector coplanar with hati + hatj + 2 hatk and hati + 2 hatj + hatk, and perpendicular to hati + hatj + hatk is : a) ((hatj - hatk )/( sqrt2)) b) ((hati + hatj+ hatk )/( sqrt3)) c) ((hati + hatj + 2 hatk )/( sqrt6)) d) ((hati + 2 hatj + hatk )/( sqrt6))
