Problem 2 An electron and a proton are released from rest midway between two oppositely charged parallel plates. The mass of electron $m_e = 9.11 \times 10^{-31}$ kg and $e^- = -1.60 \times 10^{-19}$ C while the proton has mass $m_p = 1.67 \times 10^{-27}$ kg, $e^+ = +1.60 \times 10^{-19}$ C. The plates are vertical and parallel 1.7 cm apart from each other with a potential difference of 6V to +12V. A. Draw a well labelled diagram representing the system, clearly indicating the direction of the electric field. B. Determine the magnitude of the electric field between the plates. C. State which particle or particles will accelerate to the 6V plate. D. Explain with proof why the electron reaches the charged plate before the proton. E. Calculate the kinetic energy of the proton when it reaches the plate.

Assessment Question #8 A proton enters a region between two large parallel plates made of aluminum separated by a distance of 2.00 cm and kept at a potential difference of 200 V. The proton enters through a small hole in the negative plate and moves towards the positive plate, stopping halfway between the plates. Assuming the electric field between the plates is uniform, find the speed of the proton as it initially passes through the small hole in the negative plate.
