Question

Prove that vector a=i^+2j^+3k^ and vectorb=2i^-j^ are perpendicular to each other

Answer 1

Answer:Yes, they are perpendicular.

Explanation:

i^ indicates x axis and j^ indicates y axis respectively.

So now looking at the equation and considering vector a as constant the direction of b w.r.t. a are opposite in the respective planes. Hence they are perpendicular.
