An electron in an atom is a distance 2.42 x 10-11 m from the nucleus of the atom. The nucleus of the atom contains 10 protons.

1. Calculate the electric field at the position of the electron due to the charges present in the nucleus. Take Coulomb's constant, k = 8.99 x 109 N m2 C-2

2. Calculate the force experienced by the electron when it is 2.42 x 10-11 m away from the nucleus.

3. In which direction does the force on the electron act?

4. When the electron moves into an excited state, it moves further away from the atom. In one of these excited states, the electron is at a point where the electric potential, due to the nucleus, is 336 V (3 s.f.). Calculate the distance between the nucleus and the electron in the excited state.

5. Calculate the electrical potential energy of the electron when it is in the excited state.
