4. [20 pts) Muons are negatively charged particles, with the same charge as electrons Q = e, that shoot toward Earth from space at incredible speeds. Thunderstorm clouds have a charge separation within them generating a large electric eld which we will approximate as a parallel plate capacitor. {a} {5 pts) A muon travels through a thunderstorm cloud and is perpendicular to the parallel "plates." Once the muon passes through the plates it loses 2.1 x 10-10] of kinetic energy. What is the voltage difference across the thundercloud? (b) (5 pts) If the distance between separated charges in the thundercloud is 20, 000m what is the electric field inside the cloud?(c) (5 pts) If the cloud has an area of 10 m, what is the cloud's capacitance?(d) (5 pts) How much charge is stored in the cloud
