An electron travels through uniform magnetic and electric fields. The electron has speed [v] m/s in the negative z-direction. The x-component of the electric field is [E] N/C. If the net force on the electron is zero, what is the y-component of the magnetic field (including sign) in T?

An electron travels through uniform magnetic and electric fields. The electron has speed [v] m/s in the negative z-direction. The x-component of the magnetic field is [B] T. If the net force on the electron is zero, what is the y-component of the electric field (including sign) in N/C?
