An electron has a speed of 3.75 Mm/s and is ejected northward inside a particle accelerator. If the path traced is clockwise, find (a) the magnitude and direction of the magnetic field that will cause the electron to follow a semicircular path (the diameter of the semicircle is 37.5cm), (b) the time required for the electron to complete a semi-circular path (note that t = f^(-1)), and (c) find the magnetic force at time t.
