an electron is projected with an initial speed vo=2.00*10^6 m/s into the uniform field between between two parallel plates.Assume that the field between the plates is uniform and directed vertically downward and that the field outside the plate is zero.the electron enter the field at a point midway between the plates.(a)if the electron just misses the upper plate at it emergs from the field find the magnitude of the electric field. (b)suppose that the electron is replaced by a proton with the same initial speed vo.would be the magnitude and direction of it vertical displacement as it exits between the plates?(c)compare the paths traveled by the electron and proton and explain the differences.(d)discuss whether it is reasonable to ignore the effect of gravity
