Surfing For Physics Formulas For Force?

Susan asks…Physics, Electrostatic Force?Two tiny, spherical water drops, with identical charges of -9.20E-17 C, have a center-to-center separation of 1.9 cm.
(a) What is the magnitude of the electrostatic force acting between them?
Also,
(b) How many excess electrons are on each drop, giving it its charge imbalance?



Show work please.Nancy answers:Hi Dear!
............................................
Part (a):We must use formula below:
F=kqQ/r^2
F: Electrostatic force,We want
