An Electron Moves Through a Region of Crossed Electric and Magnetic

An electron moves through a region of crossed electric and magnetic fields.The electric field E = 3381 V/m and is directed straight down.The magnetic field B = 0.77 T and is directed to the left.For what velocity v of the electron into the paper will the electric force exactly cancel the magnetic force?

A) 4400 m/s
B) 2600 m/s
C) 4200 m/s
D) 5200 m/s
E) ​7000 m/s
