A parallel plate capacitor of `300 muF` is charged to `200 V`. If the distance between its plate is halved, what will be the potential difference between the plates and what will be the change in stored energy ?

A capacitor with a capacitane of 50muF is connected to 200V, if the distance between its plates is halved, what will be the potential between the plates and what will be the change in energy stored in it?

A parallel plate capacitor of capacity 100 muF is charged to 500 V. If the distance between the plates is halved, what will be the new potential difference and the change of stored energy?

A parallel plate 300 mu F capacitor is charged to 200 V, and is then disconnected from the source. If the distance between its plates is halved, what will be the potential difference between the plates and the change in energy stored in it?

The plates of a parallel plate capacitor are charged up to 200 V. A dielectric slab of thickness 4 mm is inserted between its plates. Then, to maintain the same potential difference between the plates of the capacitor, the distance between the plates increased by 3.2 mm. The dielectric constant of the dielectric slab is
