A small block of mass m An electron is accelerated from rest through a potential difference V. This electron experiences a force F in a uniform magnetic field. On increasing the potential difference to V' having charge q the force experienced by the electron in the same magnetic field becomes 2F. Then the ratio (V'/V) is equal to
