Question

if vertical component of a vector is equal to its horizontal component the angle made by the vector with x-axis

Answer 1

Thank you for asking this question. Let me provide you with a solution for this question. 

When a force is acting diagonally to a plane it always has two components. One with the x-axis (horizontal) and other with the y-axis (vertical).
The one with x-axis is usually Fcos(θ) and the one with y-axis is usually Fsin(θ) where θ is the angle between the plane and the force and F is the diagonal force.
So for the vertical and horizontal component to be equal the angle should be 45 degrees with the x-axis as only the sin and cos theeta would be equal.

I hope my solution clarifies your problem and helps you in some manner.
