what are the forces on two charges of +0.44c and +2.4c, if they are separated bu=y a distance of 3.16cm? repel or attract each other?
If those charge are Coulombs, the force is huge.
F = k Q1*Q2/R^2
where k is Coulomb's constant (about 9*10^9 in SI units) and R = 0.0316 m
F = 9.5*10^12 N
Are you sure they did not mean microcoulombs?
