Two charges exert a force of 10 N on each other when separated by a distance 0.2 m in air. When they are placed in another medium of dielectric constant K = 4 , and separated by distance R. they exert same force. The distance R equats to

The capacitance of a parallel plate capacitor having air between its plates is 10 mu f . if the distance between the plates is reduced to half and the medium between plates is replaced by a medium of dielectric constant k=5 , then find the value how much increase or decrease in the capacitance of the capacitor.

A capacitor of capacitance C is charged to potential difference V and then disconnected from the battery. The air dielectric of capacitor is replaced by another dielectric of dielectric constant K. The fractional decrease in energy of the capacitor is

Assertion: If the meduim between two charges is replaced by another medium of grater dielectric constant then the electric force between them decreases. Reason: Electric dipole moment varies inversely as the dielectric constant.

A parallel plate capacitor having a separation between the plates d, plate area A and material with dielectric constant K has capacitance C_(0) . Now one-third of the material is replaced by another material with dielectric constant 2K, so that effectively there are two capacitors one with area 1/3A, dielectric constant 2K and another with area 2/3A and dielectric constant K. If the capacitance of this new capacitor is C then (C)/(C_(0) is

The capacity of a capacitor becomes 10 mu F when air between the plates is replaced by a dielectric slab of K = 2. What is the capacity of the condenser with air in between the plates ?
