Within the green dashed circle shown in the figure below, the magnetic field changes with time according to the expression 8 - 2.001 - 1.00r? 0.100, where his interest on seconds, and R210 cm *** (a) Whent 200 s, calculate the magnitude of the force exerted on an electron located at point which is at a distance 420 cm from the center of the circular field region (b) When - 2.00 s, calculate the direction of the force exerted on an electron located at polit Ps which cancer, 20 on 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 nero? (Consider the time after t=0)
