I'm having trouble with these two problems on my physics homework. Any help would be appreciated.
1. Two charged spheres each containing a quantity of excess electrons equal in number to Avogadro's number are separated by 1000 km in vacuum. Compute to two significant figures the electrical interaction between the spheres.
2. Two protons are fired directly at each other in a vacuum chamber. What is the force each experiences at the instant they are 1.1 10-14 m apart? [Hint: The particles are identically charged and will experience a Coulomb repulsion.]

Use Coulomb's law
1 q1 = q2 = 6.02 x 10^23 x 1.6 x 10^-19 coulombs
d = 10^6 m
2 q1 = q2 = 1.6 x 10^-19
Plug in the numbers
