A long solenoid has a diameter of 12.0 cm. When a current i exists in its windings, a uniform magnetic field of magnitude B = 43.6 mT
is produced in its interior. By decreasing i, the field is caused to decrease at the rate of 6.67 mT/s. Calculate the magnitude of the
induced electric field (a) 2.95 cm and (b) 9.54 cm from the axis of the solenoid.
