Induced Electric Fields: for a Long Ideal Solenoid Having a Circular

Induced electric fields: For a long ideal solenoid having a circular cross-section, the magnetic field strength within the solenoid is given by the equation B(t) = 5.0t T, where t is time in seconds. If the induced electric field outside the solenoid is 1.1 V/m at a distance of 2.0 m from the axis of the solenoid, find the radius of the solenoid.

A) 0.30 m
B) 77 m
C) 0.94 m
D) 9.0 m
