A magnetic field directed into the page changes with time according to B = 0.0250 t2 + 1.40, where B 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 = 2.20 s and r2 = 0.0200 m, what is the magnitude of the electric field at point P2? N/C (b) When t = 2.20 s and r2 = 0.0200 m, what is the direction of the electric field at point P2? perpendicular to r2 and counterclockwise into the page perpendicular to r2 and clockwise out of the page
