The gravitational force F between two bodies of masses m1 an

The gravitational force F between two bodies of masses m₁ and m₂ is given by the equation F = Gm₁m₂/r² where G is the gravitational constant (6.674×105// Nm0/kg0), m₁ and m₂ are the masses of the bodies in kilograms, and r is the distance between the centers of mass of the two bodies. Write a function to calculate the gravitational force between two bodies given their masses and the distance between them. Test your function by determining the force on a 1200 kg satellite in orbit 49,000 km above the center of mass of the Earth (the mass of the Earth is 5.972× 100= kg). You must include a proper comment header block and you must use good programming practices
