How far apart the two electrons be, if the force between them equals the weight of an electron? What in case of protons?

Dear Abhijeet

k e^2 / r^2 = m g
r = e [k / (m g)]^1/2
then
1) r = 1.6x10^-19 [9x10^9 / (9.1x10^-31*9.8)]^1/2 = 5.08 m [electrons]
2) r = 1.6x10^-19 [9x10^9 / (1.67x10^-27*9.8)]^1/2 = 0.12 m [protons]

by force balance

ke2/r2=mg

thenput the values of charge fo protons and

r = 1.6x10^-19 [9x10^9 / (9.1x10^-31*9.8)]^1/2 = 5.08 m [electrons]
2) r = 1.6x10^-19 [9x10^9 / (1.67x10^-27*9.8)]^1/2 = 0.12 m [protons]
