Question

The gravitational attractive force between two bodies with masses m1 and

m2 separated by a distance d is given by:

F = Gm1m2

d 2

where G is the universal gravitational constant:

G = 6.673 × 10−8 cm3

g × sec2

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

ies and the distance between them and that returns the gravitational force.

Since you will use the preceding formula, the gravitational force will be in

dynes. One dyne equals

g × cm

sec2

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.

Answer 1

Code -

#include <iostream>

using namespace std;
//constant declare for GRAVITATIONAL constant
const double GRAVITATIONAL = 6.6742E-8;

//FUNCTION TO CALCULATE Gravitational FORCE
double gravitationalForce(double mass1, double mass2, double distance){
//calculate Gravitational force
double gForce = (GRAVITATIONAL*mass1*mass2)/(distance*distance);
return gForce;
}
int main()
{
//variable declare
double gForce,mass1,mass2,distance;
//ask user for first body mass
cout<<"Enter mass of first body "<<endl;
cin>>mass1;
//ask user for second body mass
cout<<"Enter mass of second body "<<endl;
cin>>mass2;
//ask use for distance between 2 bodies
cout<<"Enter distance between 2 bodies "<<endl;
cin>>distance;
//calculate gravitational force
gForce = gravitationalForce(mass1,mass2,distance);
//print the result
cout<<"Gravitational Force between 2 bodies is "<<gForce;

return 0;
}
