... 9. 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 V1 , the force experienced by the electron in the same magnetic field becomes 2F. then, the ratio (V1/V) is equal to ...
