A uniform magnetic field of 1.5 T exists in a cylinderical region of radius 10.0 cm, its direction being parallel to the axis along east to west. A current carrying wire in north-south direction passes through this region. The wire intersects the axis and experience a force of 1.2N downwards. If the wire is turned from north south to northest-southwest direction. then magnitude and direction of force is

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