Answer 2

Explanation:

Let p=b,q=a,R=a (given),theta is the angle between a and b.

In the second case,p=b,q=2a,phai is the angle made by R with 2b or b (directions of b and 2b are the same)

To prove R and b are perpendicular to each other.

The relevant calculations have clearly been shown above.
