Exercise: Gravitational Force

Let's calculate the gravitational force between two masses!

Problem Statement

Gravitational force is the attractive force that exists between two masses. It can be calculated by using the following formula:

GMmr2\dfrac{G Mm}{r^2}

where G is the gravitational constant, M and m are the two masses, and r is the distance between them.

You must implement this equation in Python to calculate the gravitational force between Earth and the moon.

Sample Input

G = 6.67 * 10-11

MEarth = 6.0 * 1024

mMoon = 7.34 * 1022

r = 3.84 * 108

Sample Output

FG = 1.99 * 1020

Coding Challenge

All the values have already been given to you. You must write the formula in Pythonic syntax and store the answer in the grav_force variable.
