(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

vector A,B and C are mutually perpendicular unit vectors , then |vect.A + Vect.B + Vect.C| is equal to .....???

2. Relevant equations

unit vector=vector/magnitude

3. The attempt at a solution

since they are unit vectors and are perpendicular..they obviously are lying along x , y and z axes denoted by i , j , k (caps)
