If you combine Archimedes' laws of lever with Newton's gravity and Coulomb's law you'll see that the last are not quite accurate.
\frac{F_1}{F_2}=\frac{M_1}{M_2}=\frac{D_2}{D_1}
is the Archimedes' law of lever.

Problem 11.
Find the magnitude electric field at a point midway between two charges of 34.4*10^9 C and 78.6*10^-9 C separated by a distance of 58.2 cm. Answer in N/C.
Note: Do i use coulomb's law? If so, when i multiply the constant to the quiotent is that my answer?
Problem 14.
An...
Yeah, I'm having difficulties with this one question...
A stationary proton holds an electron in suspension underneath it against the force of gravity. How far below the proton would the electron be suspended?
I understand that Fe = Fg
so i would have __ = mg...
but i don't know what...
