a. Calculate the voltage sensitivity of the cathode ray tube of the oscilloscope,
i.e. the offset of the spot on the screen caused by the voltage of 1 V on the
control plates. The length of the plates l, the distance between them d ≪ l,
the distance from the end of the plates to the screen L ≫ l. Accelerating
voltage V.
b. Determine the sensitivity of the cathode ray tube if V = 10 kV, L = 30 cm,
l = 3 cm, d = 5 mm.
