Q. The largest apple pie ever made was rectangular in shape and had an area of 7m× 12m. Consider a parallel-plate capacitor with this area. Imagine that the capacitor is filled with air and the distance between the plates is 1mm. a. What is the capacitance of the capacitor? b. What potential difference would have to be located across the capacitor for it to store 1J of electrical potential energy?

Q. How much kinetic energy will the electron gain (in joules and eV) if it accelerates through a potential difference of 27,000 V in a TV picture tube?
