In a Coolidge tube, electrons strike the target and stop inside it. Does the target get more and more negatively charged as time passes?

An electron passes between two parallel plate of a capacitor as shown in the diagram. The electron enters the plate at t=0 and it comes out of the plates at time t=T. The electron hits the screen at A, as shown. Now a time varying potential difference V is applied between the plates, as shown in the graph. (Neglect the gravity). The point where the electron now will strike (as compared to point A) will be

The probability of an event that person hits the target is (1)/(4) . He hits target at least n times. The probability that to hit target n times is more than (2)/(3) then minimum value of n is ........

In an X-rays tube, electrons striking a target are brought to rest, causing X-rays to be emitted. In a paricular X-ray tube, the maximum frequency of the emitted continuum X-ray spectrum is f_(o) . If the votage across the tube is doubled, the maximum frequency is

When a negative charged rod is brought near, but does not touch, the initially unchanged electroscope shown below, the leaves spring apart (I) . When the electroscope is then touched with a finger, the leaves collapse (II) . When next the finger and finally the rod are removed, the leaves spring apart a second time (III) . The charge on the leaves is

Statement-1 If the accelerating potential in an X-ray tube is increased, the wavelength of the characterstic X-rays do not change. because Statement-2 When an electron beam strikes the target in an X-ray tube, part of the kinetic energy is converted into X-ray energy.

The unpaired electrons in AI and sI are present in 3p orbital . Which electron will experience more effective nuclear charge from the nucleus ?
