At a place, the horizontal component of earth's magnetic field is V and angle of dip is `60^(@)`. What is te value of horizontal component of earth's magnetic field at equator ?

Explanation

To solve the problem, we need to find the value of the horizontal component of the Earth's magnetic field at the equator, given the horizontal component at a certain place and the angle of dip.

### Step-by-Step Solution:

1. **Understand the Given Information**:
- The horizontal component of the Earth's magnetic field at a certain place is denoted as \( V \).
- The angle of dip (\( \delta \)) at that place is \( 60^\circ \).
