Physics 30. It would be awesome if you explain with images esp. for the last question. Thank you!

A cathode ray tube emits a stream of electrons at a screen 1.00m away. The tube is aligned so the electron stream hits the screen dead center, at the intersection of the '+'. A solenoid is then placed beneath the cathode ray tube which produces a magnetic field of 1.10 x 10" T. This causes the electrons to deflect to the right and hit the screen at position 1 instead. Im from CRT to side view screen end view potential difference cathode fay tube solenoid (The screen actually faces the cathode bench ray tube. This shows the screen as you would see it if you stood behind the CRT.) The electrons that make up the beam were accelerated from rest through a potential difference I at the left edge of the CRT, just before they enter the magnetic field. If the acceleration of the electrons in the magnetic field is 9.08 x 10# *m/s, determine the potential difference required to accelerate the electrons. (4 marks) The CRT is aligned so that the electrons in the beam are initially moving horizontally. Even when you look very closely, you are not able to see any downward bending of the electron beam; it seems as if the electrons are not affected by gravity. Explain why you cannot see the electrons drop on their way to the screen. (2 marks) Use the following information to answer the next bullet. The formula for the magnetic field from a solenoid is B = Moln where, B represents the magnetic field strength of the solenoid Mo is a constant, I represents the current through the solenoid n represents the number of loops per meter length. The electron beam is then made to strike the screen at position 2. What two changes were made to the current in the solenoid? State how each change in the solenoid wil affect the electron beam. Use the formulas for a solenoid and magnetic force on a charged particle to support your answer. (3 marks) side view end view
