Electrostatic Potentials and Capacitance

268019 A parallel plate condenseris charged by connecting it to a battery. The battery is disconnected and a glas slab is introduced between the plates. Then

1 potential increases
2 electric intensity increases
3 energy decreases
4 capacity decreases
Electrostatic Potentials and Capacitance

268021 A parallel plate capacitor of capacity\(\mathrm{C}_{0}\) is charged to a potential \(\mathrm{V}_{\text {. }}\).
A) The energy stored in the capacitor when the battery is disconnected and the plate separation isdoubled is \(E\).
B) The energy stored in the capacitor when the charging battery is kept connected and the separation between the capacitor plates is doubled is \(E_{2}\). Then \(\frac{E_{1}}{E_{2}}\) value is

2 \(3 / 2\)
3 2
4 \(1 / 2\)

268023 A variable parallel plate capacitor and an electroscopeare connected in parallel to a battery. The reading of the electroscope would be decreased by

1 increasing the area of overlap of the plates
2 placing a block of paraffin wax between the plates
3 decreasing the distance between the plates
4 decreasing the battery potential
