Problem

When an electron is accelerated through a potential difference VV, it experiences a force FF in a uniform transverse magnetic field. If the potential difference is increased to 2V2V, the force experienced by the electron in the same magnetic field is: (a) 2F2F (b) 22F2\sqrt{2}F (c) 2F\sqrt{2}F (d) 4F4F
