Problem

An electron beam travels horizontally from west to east with speed 2.5×106 m s−12.5\times10^{6}\,\text{m s}^{-1}. A uniform magnetic field of 5.0×10−2 T5.0\times10^{-2}\,\text{T} is applied vertically upward in the same region. (a) Determine the magnitude of the uniform electric field required so that the electrons emerge undeflected. (b) State whether this electric field should be directed toward the north or the south.
