Magnetic Effects of Current and Magnetism Part 2

An electron with kinetic energy 5‌eV enters a region of uniform magnetic field of 3µT perpendicular to its direction. An electric field E is applied perpendicular to the direction of velocity and magnetic field. The value of E, so that electron moves along the same path, is ______ NC−1.
(Given, mass of electron =9×10−31‌kg, electric charge =1.6×10−19C )
