(Physics) Coulomb’s Law states that the force, F, acting between two electrically charged spheres is given by this formula:

q1 is the charge on the first sphere.

q2 is the charge on the second sphere.

r is the distance between the centers of the two spheres.

k is a proportionality constant. 

Write an assignment statement to calculate the force, F.
