A parallel plate capacitor (of capacitance C) with circular plates of radius r0 located at positions ±α, is connected in series with a resistor R and is charged by a battery of voltage V. Consider a circular loop L of radius ‌

parallel to the capacitor plates is located at the center. Which of the following statements is correct?

The charge on the capacitor at time t is q(t)=CR(1−e−t∕(CV))
The charge on the capacitor at time t is q(t)=CV(1−e−t∕(CV))
The flux through the loop L is independent of the area enclosed by it
The magnetic field is directed orthogonal to the loop L
The magnetic field is directed along the loop L
