Question

The answers are B and C.

Please explain how you came to your conclusions!

This question and the next one concern the following situation: A constant current I is supplied for a brief time to charge a parallel plate capacitor. The capacitor has circular plates of radius R with a gap d (d R). Point 1 is at a distance R + d from the wire, and point 2 is at a distance R + d from the center of the capacitor. During the time interval that the constant current I is flowing through the capacitor, the magnetic field at point 2, B2 is: B2>B1 B2 = Bl 0

Explanation / Answer

a.

this is because since d is very less than R,so the magnetic field will be olmost only due to the current carying wire and will very less be affected by moving charge on plate.

When a capacitor is charged, the electric field E, and hence the electric flux Phi, between the plates changes. This change in flux induces a magnetic field, according to Amp
