In this problem, we are dealing with current, number fo protons, and the time.
Current and time are related by:
where Q is the charge, i is the current, and t is the time.
In proton beam therapy, a beam of high-energy protons is used to deliver radiation to a tumor, killing its cancerous cells. In one session, the radiologist calls for a dose of 4.9×108 protons to be delivered at a beam current of 120 nA.
How long should the beam be turned on to deliver this dose?
