Question

Given P bar +Q bar =Rbar then p²+q²=r² then​

Answer 1

Answer:

Pbar and Qbar are perpendicular.

Explanation:

Step-1:

Take the given equation and apply S. O. B. S(Squaring on both sides).

Step-2:

Then apply given second equation to it, then we get Pbar. Qbar(DOT PRODUCT) =0.This dot product is zero only when they are perpendicular.

So, we can conclude that Pbar and Qbar are perpendicular.
