Crossed electric and magnetic fields are established over a certain region. The magnetic field is 0.671 T vertically downward. The electric field is 2.06 x 106 V/m horizontally east. An electron, traveling horizontally northward, experiences zero net force from these fields and so continues moving in a straight line. What is the electron's speed?
