Physics electromagnetism word problem? please?
A negative charge is propelled with a velocity of 2.9e6 m/s toward the top of the page through a 6.2e-2 T magnetic field directed to the left by a 3.4e-12 N force. How many electrons are on the charge moving through the magnetic field?? I found the current and resistance...but i cant figure out the electron number... it says its 118
