1g of hydrogen contains 6.02*10^23 atoms, each with one electron and one proton.?

Question

1g of hydrogen contains 6.02*10^23 atoms, each with one electron and one proton. Suppose 1g oh hydrogen is separated into protons and electrons, that the protons are placed at the Earth's north pole, and the electrons are placed at Earth's south pole. Find the magnitude of resulting compressional force on Earth. (The radius of earth is approximately 6.38*10^5m).

Answer 1

F=k q(1)q(2)/d^2
d is diameter of earth d=2* radius

q(1)= -q(2)=(6.023 *10^23 ) * (1.6*10^-19)

k =9*10^9

Answer 2

See
