A circular region (radius R = 3.98 m) has a magnetic field perpendicular to the plane of the circle, with magnitude given by: B = 6.243 + 82.1t2 - 5.65, where B is in T and t is in seconds. At time t = 3.66 s, find the magnitude of the force, in N, felt by stationary charge q = 868 µC placed d = 7.4 m from the center of the circle (outside the circle). Give the answer as a positive if the force is to the right, and negative if the force is to the left.
