If vector Ā=5i+3j and B= -3i+2j then magnitude of vector A+B will be

A=4i+4j-4k and B=3i+j4k , then angle between vectors A and B is

Let a=2i+2j+k and b be another vector such that a*b=14" and "a times b=3i+j-8k then the vector b is equal to

If vec a=i+2j+k,vec b=2i+j and vec c=3i-4j-5k, then find a unit vector perpendicular to both of the vectors (vec a-vec b) and (vec c-vec b)

Consider the vectors a = i- 2j + k and b= 4i- 4j + 7k What is the vector perpendicular to both the vectors?

If a=i+j-k,b=i-j+k and c is a unit vector perpendicular to the vector a and coplanar with a and b,then aunit vector d perpendicular to both a and c is
