2r/a A quantum-mechanical treatment of the hydrogen atom shows that the electron in the atom can be treated as a smeared-out distribution of negative charge of the form P(r)=-Poe Here, r represents the distance from the centre of the nucleus and a represents the first Bohr radius which has a numerical value of 0.0529 nm. Calculate the electric field at any distance r from the nucleus.
