Chapter 3, Problem 4PP

The gravitational attractive force between two bodies with masses $m_1$ and $m_2$ separated by a distance d is given by the following formula:

$F=\frac{G{m}_1{m}_2}{d^2}$

where G is the universal gravitational constant:

$G=6.673\times {10}^{-8}{\text{cm}}^{\text{3}}/\left(g\cdot {\sec }^2\right)$

Write a function definition that takes arguments for the masses of two bodies and the distance between them and returns the gravitational force between them.

Since you will use the previous formula, the gravitational force will be in dynes. One dyne equals a

$\text{g}\cdot \text{cm}/{\sec }^2$

You should use a globally defined constant for the universal gravitational constant. Embed your function definition in a complete program that computes the gravitational force between two objects given suitable inputs. Your program should allow the user to repeat this calculation as often as the user wishes.
