2 parter, THX

1) The magnetic field in a long solenoid of diameter d = 12.0 cm is decreasing at a rate of 4.50 mT/s (due to the current being gradually reduced). What is the magnitude of the induced electric field at a distance r = 3.0 cm from the axis of the solenoid? Give your answer in µV/m.

2) The magnetic field in a long solenoid of diameter d = 12.0 cm is decreasing at a rate of 3.50 mT/s (due to the current being gradually reduced). What is the magnitude of the induced electric field at a distance r = 8.5 cm from the axis of the solenoid (which is outside the solenoid)? Give your answer in µV/m.
