**drwls**, Wednesday, February 10, 2010 at 6:49pmExponents in the denomimator get subtracted from the exponents in the numerator.

3E -9 is a computer programmer's way of writing 3*10^-9. We don't use that notation here.

3*10^-9 N / 1.25*10^-19 C = (3/1.25)*10^10 = 2.4*10^10 N/C (or Volts per meter)

N/C is a measure of electric field strength
