`vec A=6hati+5hatj and vec B=(4hati-3hatj)` then `(vec A+vec B).(vec A-vec B)=`

vec A=6i+5j and, vec B=(4i-3j) ,then (vec A+vec B)*(vec A-vec B)=

If vec(A)=hati +hat j and vec(B)=hati-hatj The value of (vec(A)+vec(B)).(vec(A)-vec(B)) is :

If vec a=3hati-hatj+4hatk, vecb=2hati+3hatj-hatk and vec c=-5hati+2hatj+3hatk , then vec a.(vecb xx vec c) is

Given : vec A =2hati +3hatj and vec B = hati +hatj . What is the component of vector vec A along the vector vec B ?

If veca = hati +hatj , vecb = 2hatj - hatk " and " vecr xx veca = vecb xx vec a , vecr xx vec b = veca xx vec b , then what is the value of (vec r)/(|vec r|)

Let vec a=hati+2hatj-hatk , vec b=hati-hatj , vec c=hati-hatj-hatk ,and vecrxxveca = vecc xx veca , vecr*vecb=0 . Find vecr*veca

If vec A=hati +7hatj +hatk and vec B =2 hati+3hatj +4hatk then the component of vec A along vec B is

Given : vec A = hati + hatj +hatk and vec B =-hati-hatj-hatk What is the angle between (vec A - vec B) and vec A ?

If veca = 3hati - hatj - 4hatk , vecb = -2hati + 4hatj - 3hatk and vec c = hati + 2hatj - hatk then |3veca - 2vec b + 4vec c | is equal to

Let veca=2hati-3hatj and vecb=3hati+2hatj. Is |veca|=|vecb|? Are the vectors vec a and vec b equal?
