Two point charges are 10.0 cm apart and have charges of 2.0 μC and –2.0 μC, respectively. What is the magnitude of the electric field at the midpoint between the two charges?

8.99*10^9(2*10^-6/.025)=719200

Two equal charges are separated by 3.7 x 10-10 m. The force between the charges has a magnitude of 2.37 x 10-3 N. What is the magnitude of q on the charges?

1.9x10^-16 (I got this using Coulomb's Law and working backward)
