Question

Two vectors A and B of magnitudes 10 units and 12 units are anti-parallel. Determine A + B and A – B.

Answer 1

Explanation:

here a+b=magnitude of(b-a)

= 12-10

= 2

dont know about A-B

Answer 2

Answer:

A+B=-2

A-B=22

Explanation:

when vectors are said to be anti parallel it means they are in opposite direction magnitude does not need to be same

So,

A-B= 10-(-12)=22

A+B= 10+(-12)=-2
