Doubling the magnetic field in a proton cyclotron changes the maximum kinetic energy of the protons by what amount?
A) It is quadrupled.
B) It is doubled.
C) It remains the same.
D) It is halved.
E) It is quartered.

Question

Quizplus · Accepted Answer

The maximum kinetic energy of protons in a cyclotron is directly proportional to the square of the magnetic field. Therefore, if the magnetic field is doubled, the maximum kinetic energy of the protons is quadrupled.
