1.	The Deflection Sensitivity of a Cathode Ray Tube is1. Directly proportional to the deflection voltage2. Directly proportional to the square of the deflection voltage3. Inversely proportional to the deflection voltage4. Independent of the deflection voltage
Answer» Correct Answer - Option 4 : Independent of the deflection voltage Deflection sensitivity of a cathode ray tube is defined as the deflection of the screen per unit deflection voltage. \(s = \frac{D}{{{E_d}}} = \frac{{L{t_d}}}{{2d\;{E_a}}}m/v\) Where, L = distance between screen and centre of the deflecting plates D = Distance between deflecting plates L_d = Length of deflecting plates E_a = Accelerating voltage E_d = Potential between deflecting plates It is clear that, sensitivity is independent of deflection voltage.

Answer» Correct Answer - Option 4 : Independent of the deflection voltage

Deflection sensitivity of a cathode ray tube is defined as the deflection of the screen per unit deflection voltage.

\(s = \frac{D}{{{E_d}}} = \frac{{L{t_d}}}{{2d\;{E_a}}}m/v\)

Where,

L = distance between screen and centre of the deflecting plates

D = Distance between deflecting plates

L_d = Length of deflecting plates

E_a = Accelerating voltage

E_d = Potential between deflecting plates

It is clear that, sensitivity is independent of deflection voltage.
