(c) An electron beam in an electrostatic cathode-ray tube travels at a velocity of 18 X 10m/s and is deflected 10 cm from the initial direction of travel. The tube has deflection plates 2 cm long and 3.5 mm apart and a deflection factor of 2.7 V/mm. Taking mass of electron, m = 9.1 X 10 kg, electronic charge, e = 1.6 X 10-1°C, determine the (1) (11) (iii) (iv) value of the final anode voltage; deflection sensitivity of the tube; distance of the screen from the centre of deflecting plates, Value of the voltage across the deflecting plates.
