Question

Prove that vector a*b will be perpendicular
to vectors a and b if vector a=3i-j+2k
and b=2i-j+k​

Answer 1

Step-by-step explanation:

I just tell u the Process.

1. You have to find the cross Product of a and b vector
2. the you find the the vector c from a*b
3. then do the dot Product of a and c vector
4. then do the same thing with b and c vector
5. you find that both of the answer is zero
