Question

If the component of one vector in the direction of another vector is zero, then
those two vectors
are parallel to each other
are perpendicular to each other
are opposite to each other
are coplanar vectors​

Answer 1

Answer:

Perpendicular to each other.

Explanation:

Consider a vector A, another vector B perpendicular to A.

Then the component of vector B in the direction of A is

Bx = B cos ($\alpha$)

Since both vectors are perpendicular so angle is 90 degree.

$\alpha$Bx = B cos(90) = 0

So, component of B in the direction of A is zero, if both vectors are perpendicular to each other.
