A CRO has an anode voltage 3000 V and parallel deflection plate 3 cm long and 7 mm apart. The screen is 35 cm from the centre of the plates. Find the input voltage required to deflect the beam through 4 cm. The input voltage is applied to the deflecting plates through amplifiers having an overall gain of 100.
Enter numerical value using the virtual keypad. Round off where necessary.
