A magnetic field directed into the page changes with time according to 8 = 0.019 Of + 1.40, where 8 is in teslas and t is in seconds. The field has a circular cross section of radius R = 2.50 cm (see figure below). (a) When t = 4.60 s and r, = 0.020 0 m, what is the magnitude of the electric field at point P,? 0,00156 X N/C (b) When t = 4.60's and r, = 0.020 0 m, what is the direction of the electric field at point P.? O out of the page O perpendicular to r, and counterclockwise O perpendicular to r, and clockwise O into the page
