Kaplan 10th Edition DT Q42

Kaplan's Book

42) In this problem, we are asked to find the magnitude of the charge given the magnetic field magnitude, the charge's velocity, and the magnetic force it experiences. We need to take a look at the formula for magnetic force.

Where F[B] is the magnetic force, B is the magnetic field, q is the charge, and v is the velocity

Since we are already given all the other variables, we can plug in our values and solve for the charge(q).

Where F[B] is the magnetic force, B is the magnetic field, q is the charge, and v is the velocity

Answer: B
