In Thomoson's experiment a p.d. of 500 volts is applied and deflection of spot is obtained on the fluorescent screen. To bring the spot to the original position a magnetic induction (B) of magnitude of 1 x 10-2 Wb/m² was required. Determine the velocity of electrons if the distance between the plates is 0.5 cm.
