Electric force exactly cancel the magnetic force

Reference no: EM13563409

An electron moves through a region of crossed electric and magneticfields. The electric field E = 2 000 V/cm and is directedstraight down. The magnetic field B = 0.80 mT and isdirected to the left. For what velocity v of the electron into the paper will the electric force exactly cancel the magnetic force?
