In proton beam therapy, a beam of high-energy protons is used to kill cancerous cells in a tumor. In one system, the beam, which consists of protons with an energy of 2.8×10−11J, has a current of 84 nA. The protons in the beam mostly come to rest within the tumor. The radiologist has ordered a total dose corresponding to 3.2×10−3J of energy to be deposited in the tumor.
Part A
How many protons strike the tumor each second?
Express your answer as a number of protons.
Part B
How long should the beam be on in order to deliver the required dose?
Express your answer with the appropriate units.

In proton-beam therapy, 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 8.0×103 kV potential difference.

In proton-beam therapy, 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 9.0×10−2 J of proton energy in the tumor. To create the proton beam, protons are accelerated from rest through a 1.1×104 kV potential difference. What is the total charge of the protons that must be fired at the tumor?
