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.

ree
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).

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

Answer: B
