A beam of electrons after being accelerated through a

A beam of electrons after being accelerated through a potential difference of 100 volts enters into a uniform magnetic field which is perpendicular to the plane of paper and directed outwards The width of the region OM in which magnetic field is present is 2cm Till magnetic field is not switched on the electron beam moves straight forward and produces a bright spot at a point C on the fluorescent screen 6cm from the PQ which is at a distance 2 edge of the magnetic field When the magnetic field is switched on the spot shifts to a point A along the path ONA Find the displacement CA of the spot if the induction of the magnetic field B 1 5 x 10 3 Tesla 0 N M C
