What is the direction of the electric field at the corner? What is the direction of the electric field at the corner? along the line between the corner and the center of the square toward the center along the side of the square between the corner and one of the charges outward of the charge along the line between the corner and the center of the square outward of the center along the side of the square between the corner and one of the charges toward the charge

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
