1. ### If a 3μ C and a 7μ C charge is separated by 21cm, what is the force between the two charges? ?

F = k *Q1*Q2/d^2 = 9*10^9*3*7*10^-12*10^4/21^2 = 4.29 N

2. ### physics question?

F = k e^2 / r^2 F = 9x10^9 * (1.602×10^−19)^2 / (1x10^−11)^2 F = 2.31 × 10^-6 N where e =  1.602×10^−19 C is charge od proton k = 9x10^9 N m^2/ C ^2 is Coulomb's constant
