An electron at point A in the figure has a speed of 1.42×10^6 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?
