Please help with a physics problem?

Electrons move through a magnetic field of 5.0 ✕ 10-2 T balanced by an electric field of 2.4 ✕ 103 N/C. What is the speed of the electrons?

    By F(electromagnetic) = F(electrostatic)

    =>qvB = qE

    =>v = E/B

    =>v = (2.4 x 10^3)/(5 x 10^-2)

    =>v = 4.8 x 10^4 m/s
