A body weighs w Newton on the surface of the earth. Its weight at a height equal to half the radius of the earth, will be `x/y w` where x and y are coprimes . Find x and y

Explanation

To solve the problem, we need to determine the weight of a body at a height equal to half the radius of the Earth. Let's break down the solution step by step.

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