Python Program to Find the Gravitational Force between Two Objects

m1=float(input("Enter the first mass: "))
m2=float(input("Enter the second mass: "))
r=float(input("Enter the distance between the centres of the masses: "))
G=6.673*(10**-11)
f=(G*m1*m2)/(r**2)
print("Hence, the gravitational force is: ",round(f,2),"N")

Output

Enter the first mass: 1000000
Enter the second mass: 500000
Enter the distance between the centres of the masses: 20
Hence, the gravitational force is:  0.08 N
