The vertical component of a vector is equal to its horizontal component. What is the angle made by the vector with x-axis ?

Explanation

To solve the problem where the vertical component of a vector is equal to its horizontal component, we need to find the angle made by the vector with the x-axis. Let's break down the solution step by step.

### Step-by-Step Solution:

1. **Understanding the Components**:
- Let the vector be represented as \( \vec{r} \).
- The vertical component of the vector is denoted as \( V \) and the horizontal component as \( H \).
- According to the problem, we have \( V = H \).
