Sindhu wanted to know the variation in the gravitational force of attraction with height. So, she took a body of mass 'm' from the surface of the earth to a height equal to the radius of the earth. She then determined the change in gravitational force of attraction. What is her answer?

Explanation

To determine the variation in the gravitational force of attraction with height, we can follow these steps:

### Step 1: Understand the Gravitational Force Formula
The gravitational force \( F \) between two masses \( m \) (the mass of the object) and \( M \) (the mass of the Earth) at a distance \( r \) from the center of the Earth is given by the formula:
\[ F = \frac{G \cdot M \cdot m}{r^2} \]
where \( G \) is the gravitational constant.
