A body weight 63 N on the surface of the earth. What is the gravitational force on it due to the earth at a height equal to doubled the radius of the earth?

Explanation

To solve the problem, we need to find the gravitational force acting on a body at a height equal to double the radius of the Earth. Here’s the step-by-step solution:

### Step 1: Understand the Given Information
We know that the weight of the body on the surface of the Earth is 63 N. The weight (W) is given by the formula:
\[ W = mg \]
where \( m \) is the mass of the body and \( g \) is the acceleration due to gravity at the Earth's surface.
