Question

A time dependent magnetic field inside a long solenoid of radius 0.05m is given by $\overrightarrow𝐵$(𝑡) = 𝐵0 sin 𝜔𝑡 $\^z$. If 𝜔=100rad/s and 𝐵0= 0.98Weber/m2 , then the amplitude of the induced electric field at a distance of 0.07m from the axis of the solenoid is ______V/m. (Rounded off to two decimal places)

Answer 1

The correct answer is: 1.71 to 1.75 (approx)
