8- Within the green dashed circle shown in Figure, the magnetic field changes with me according to the expression B-21-4t+0.8, where B is in teslas, t is in seconds, and R-25 cm. When t-2 seconds, calculate (a) the magnitude and the direction of the force exerted on an electron located at point P. which is at a distance r- 5 cm from the center of the circular field region. (b) At what instant is this force equal to zero?
