Within the green dashed circle shown in the figure below, the magnetic field changes with time according to the expression 3 - 4.001" - 3.000.000, where is in teslas, tis in seconds, and R - 2.80 cm XXXXX XXX NXXX XXXXXX XXXXXX X X X X X (a) When - 2.00 s, calculate the magnitude of the force exerted on an electron located at point Py, which is at a distance rj - 5.60 cm from th center of the circular field region N (b) When - 2.00 s, calculate the direction of the force exerted on an electron located at point P, which is at a distance ry - 5.60 cm from the center of the circular field region tangent to the electric field line passing through point P, and clockwise tangent to the electric field line passing through point P, and counterclockwise The magnitude is zero. (c) At what instant is this force equal to zero? (Consider the time after t0 s.)
