We have a parallel plate capacitor with two plates containing charges + Q and -Q a distance d = 1.60 cm apart. We release a proton from rest at point A, just above the lower plate. At point B, just before the proton strikes the upper plate, the proton has a kinetic energy of 1.43 × 10-18 J. A proton has a mass of 1.67 × 10-27 kg and a charge of 1.60 × 10-19 C. What is the magnitude of the electric field between the plates (in V/m)?
