A body is taken to a height equal to radius of earth and then to a depth equal to radius of earth. What will be its weight in each case ?

Explanation

To solve the problem, we need to determine the weight of a body when it is taken to a height equal to the radius of the Earth and then to a depth equal to the radius of the Earth.

### Step 1: Understanding Weight at the Surface of the Earth
The weight \( W \) of a body at the surface of the Earth is given by the formula:
\[ W = m \cdot g \]
where \( m \) is the mass of the body and \( g \) is the acceleration due to gravity at the surface of the Earth.
