Question

how far apart the two electrons be if the force between them equals the weight of an electron. what is in the case of protons ​

Answer 1

Answer:

ke^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]
