Question: An electron at point A in the figure has a speed of 1.42Ã-10^6 m/s.
(a) Find the direction of the magnetic field that will cause the electron to follow the semicircular path from A to B .
(b) Find the magnitude of the magnetic field that will cause the electron to follow the semicircular path from A to B .
(c) Find the time required for the electron to move from A to B.
(d) Find the direction of the magnetic field, that would be needed if the particle were a proton instead of an electron?
(e) Find the magnitude of the magnetic field, that would be needed if the particle were a proton instead of an electron?
