2. Proton beam: A beam of protons is fired with a velocity v = 4.0 × 105m/s into a region of uniform magnetic field with B = 230 Gauss, pointing out of the page.

a) How far does the beam penetrate into the field region?

b) A uniform electric field is also turned on. What magnitude and direction for E will allow the
protons to pass through undeflected?

c) A square loop with 100 windings 10 cm on each side is free to rotate in the field. If it gains a maximum of 92 mJ as it spins, what is the current in the loop?

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. The protons gain their energy by being discharged through a type of capacitor with a potential difference of 20MV and have a starting speed of 1.88 x 10^8 m/s. Using what you know of the behavior of a point charge in an electrostatic field and the...
