Proton-beam therapy is a treatment method where a high-energy beam of protons is fired at a tumor. As the protons stop in the tumor, their kinetic energy breaks apart the tumor's DNA, thus killing the tumor cells. For one patient, it is desired to deposit 0.10 J of proton energy in the tumor. To create the proton beam, protons are accelerated from rest through a 1.1x10^4 kV potential difference. Part A: What is the total charge of the protons that must be fired at the tumor? Express your answer to two significant figures and include the appropriate units.
