Hi I need partial help with this problem….. I don’t know part B or D, trying to figure out, please help

The particles in the nucleus of an atom are approximately 1.00×10−15 m apart, while the electrons in an atom are about 1.00×10−10 m from the nucleus.

a) Calculate the electrical repulsion between two protons in a nucleus if they are 1.35×10−15 m apart

I got 126.4197 N for this

b) How many pounds would the force be?

c) If you were holding these protons, do you think you could feel the effect of this force? YES

d) Calculate the electrical attraction that a proton in a nucleus exerts on an orbiting electron if the two particles are 1.39×10−10 m apart.

e) If you were holding the electron, do you think you could feel the effect of this force? NO
