Question

What is the projection of Aon B?
(a) AB
(b) A
(c) B. A
(d) A​

Answer 1

Answer:

Here, we want the projection of vector A (OA) on the vector B (OB)

Now, component of OA along OB is OC

We have, cos x = OC / OA

So, OC = OA cos x

Therefore, projection of vector A on vector B = A cos x

Where, x is the angle between vector A and vector B
