Using Coulomb's Law, calculate the force of repulsion between a positive
charge of 110 Coulombs and another positive charge of 220 coulombs
separated by a distance of 2 meters. Use scientific notation.
(Hint: use the proportionality constant)

F = k Q1*Q2/R^2
k = 8.99*10^9
N*m^2/C^2 is the Coulomb constant
Solve for F in newtons
