# If the component of one vector A

If the component of one vector A along another vector B is equal to A. Then the two mentioned vectors are:

a) parallel to each other b) opposite to each other

c) coplanar vectors d) perpendicular vectors

Component of vector A along B = A*cos theta

Where theta is angle between A and B

So, A*cos theta = A

So, cos theta = 1

So, theta = 0°

So, vector A must be parallel to vector B
