What is the total charge of the neptunium nucleus? (The neutral
neptunium atom has 93 electrons.)
What is the magnitude of its electric field at a distance of 9.30×10-10 m from the nucleus?
What is the magnitude of the force on an electron at that distance?
What would the magnitude of the force be if the distance of the electron from the nucleus were tripled?
