Each of the protons in a particle beam has a kinetic energy of 2.20 × 10-15 j. protons in a distance of 0.920 m? answer in units of n/c. what electric field strength will stop these ld

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
