PLZ HELP, especially with question 7 A, B, and C

7. In the diagram shown, an electron is sent between charged plates at a speed of 8.00 x 10 m/s. eo 2.50 x 103 m 645 V v = 8.00 x 10 m/s a) Determine the electric field between the plates. a) 2 marks A magnetic field is set up between the charged plates in such a way that the electron passes through un-deflected. draw field v = 8.00 x 100 m/s direction here + b) In which direction do the magnetic field lines point within the charged plates? Draw directly in the box on the diagram above. 2 marks c) Determine the magnitude of this magnetic field that counters the electric field and allows the electron to pass through un-deflected.5. An electron travelling to the left at 2.2 x 10 m/s enters a magnetic field of 3.0 x 10" T that is directed out of the page, as shown in the diagram below: v = 2.2 x 10' m/s B = 3.0 x 10- T . a) Draw the resultant path the electron takes once it enters the field. I mark b) Determine the magnetic force that acts on the electron inside the field
