Question

if a=i+j+k,b=2i+3j+k find the projection vector of a and b and it's magnitude​

Answer 1

Step-by-step explanation:

If There are two vectors A and B then Projection vector is-

AB = B - A

= (2i+3j+k) - ( i+j+k )

= i + 2j + 0k

Now, the magnitude of projection vector of AB

= √(1² + 2² + 0²)

= √5
