A capacitor is connected to a battery. The force of attraction between the plates when the separation between them is halved.

A

remains the same

B

becomes eight times

C

becomes four times

D

becomes two times

Text Solution

Verified by Experts

The correct Answer is:
C
When separation becomes half `C,Q,E` becomes `2C,2Q,2E`.

Since
`F = (QE)/(2)` so `F' = (2Q.2E)/(2) F' = 4F`

A parallel plate capacitor is charged completely and then disconnected from the battery. IF the separation between the plates is reduced by 50% and the space between the plates if filled with a dielectric slab of dielectric constant 10, then the potential difference between the plates

A parallel plate capacitor of capacitance C is charged to a potential V and then disconnected with the battery. If separation between the plates is decreased by 50% and the space between the plates is filled with a dielectric slab of dielectric constant K=10 . then

While a capacitor remains connected to a battery and dielectric slab is applied between the plates, then

A parallel-plate capacitor is connected to a battery. A metal sheet of negligible thickness is placed between the plates. The sheet remains parallel to the plates of the capacitor.

A parallel plate capacitor has plate A and separation d between the plates. The capacitor is connected to a battery of emf V . (a) find the charge on the capacitor. (b) the plate separation is decreases to d//2 . Find the extra charge given by the battery to the positive plate. (c) work done in reducing separation between plates.

A parallel plate capacitor is connected to a battery and inserted a dielectric plate between the place of plates then which quantity increase

A parallel plate capacitor is charged by connecting it to a battery. The battery is disconnected and the plates of the capacitor are pulled apart to make the separation between the plates twice. Again the capacitor is connected to the battery (with same polarity) then the potential difference between the plates increases when the plates are pulled apart (yes or not)
