7. The gravitational attractive force between two bodies with masses m1 and

m2 separated by a distance d is given by:

where G is the universal gravitational constant:

Write a function definition that takes arguments for the masses of two

bodies and the distance between them, and that returns the gravitational

force between them. Since you will use the preceding formula, the

gravitational force will be in dynes. One dyne equals a

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. F Project 4.7
