If the strength of the magnetic field at A is 48 units and the strength of the magnetic field at B is 3 units, what is the distance to B? (Drawing is not to scale!)

OpenStudy (anonymous):

Force (F)= charge (q) * velocity (v) * field strength (B) Is that it?

OpenStudy (anonymous):

its 20 units... thanks @ChrisTopher987654321
