in a CRO ,fast moving electrons coming from cathode tube strikes the screen .This is seen as a single dot,but for viewing a waveform it is required that the electrons should move both horizontally as well as vertically.

The unit of deflection sensitivity of a Cathode Ray Oscilloscope (CRO) is volts per division on the vertical axis of the screen. It represents how much voltage change is needed to move the electron beam by one division vertically on the screen.

In a Cathode Ray Oscilloscope (CRO), the electron beam is deflected using an electrostatic deflection mechanism. This involves applying varying electric fields through pairs of deflection plates positioned perpendicular to the path of the beam. By altering the voltage on these plates, the trajectory of the electron beam can be controlled, allowing it to move vertically and horizontally on the screen to create the desired waveform display.
Electromagnetic deflection is used because it can create greater deflection angles of the electron beam compared to electrostatic deflection.

It is used as the horizontal deflection voltage of the CRT.
A cathode ray oscilloscope (CRO) displays electrical signals as waveforms on a screen. It consists of several key components: a cathode ray tube (CRT) that generates an electron beam, deflection systems (horizontal and vertical) to control the beam's movement, and a signal input section to process the electrical signals. The block diagram typically includes a signal input section, vertical and horizontal deflection circuits, a CRT, and a power supply. The input signal is amplified and translated into visual waveforms by controlling the electron beam's position on the phosphorescent screen.

I think you'd want just the opposite. The sweep rate is the same for both beams, so you only need one set of horizontal deflection components. But the vertical amplitudes of the two signals are generally different at the same instant of time, and you want to keep the two signals separate and distinct, so you want them running through two different vertical amplifiers.
The anode voltage does not affect the sensitivity of a CRO. The input amplifier and deflection circuit have a greater influence. The Anode voltage will affect the focus and visibility of the trace, in this respect it will affect how you see the result.
the delay line is used to delay the incoming signal vertical information and synchorized it with the horizontal
