Part A In proton-beam therapy, a high-energy beam of protons is fired at a tumor. The protons come to rest in the tumor, depositing their kinetic energy and breaking apart the tumor's DNA, thus killing its cells. For one patient, it is desired that 0.10 J of proton energy be deposited in a tumor. To create the proton beam, the protons are accelerated from rest through a 15 MV potential difference. What is the total charge of the protons that must be fired at the tumor to deposit the required energy? Express your answer with the appropriate units.

Part A Near the surface of the Earth there is an electric field of about 150 V/m which points downward. Two identical balls with mass 0.467 kg are dropped from a height of 2.37 m, but one of the balls is positively charged with g = 412 µC , and the second is negatively charged with q2=-412 µC. Use conservation of energy to determine the difference in the speeds of the two balls when they hit the ground. (Neglect air resistance.) Express your answer using three significant figures. V AEO ?
