1. A long solenoid (radius = 2.8 cm, 2300 turns per meter) carries a current given by , where is measured in s. When , what is the magnitude of the induced electric field at a point which is 2.0 cm from the axis of the solenoid?
[b]2. I used the mag field eq for a solenoid first the i used faradays law but i cant seem to get any answer in the choices.
[b]3. The attempt at a solution
