Dielectric constant of water is 40, so calculate its permittivity?

Dielectric constant of pure water is 81. Its permittivity will be

Assertion : When a dielectric is placed in an electric field, the electric field with in the dielectric as well as. Potential difference across the capacitor plates are reduced by a factor K (battery is not connected). Reason : The dielectric constant is the ratio of the absolute permittivity of the dielectric to the to the permittivity of the free space.

Dielectric constant has the same dimensions

Dielectric constant has the same dimensions as

Assertion (A) : NaCl is less soluble in heavy water than in ordinary water. Reason (R) : Dielectric constant of ordinary water is more than that of heavy water.

Two balls with equal charge are in a vessel with ice at - 10 ^@C at a distance of 25 cm from each other. On forming water at 0^@C , the balls are brought nearer to 5 cm for the interaction between them to be same. If the dielectric constant of water at 0^@C is 80 , the dielectric constant of ice at -10^@C is

C_(p) ( without dielectric ) = 2C C_(Q) ( without dielectric ) = C k and 2 k are dielectric constant of two dielectrics . Find resultant capacity between A and B .

The figure shows two identical parallel plate capacitors connected to a battery with the switch S closed. The switch is now opened and the free space between the plates of the capacitors is filled with a dielectric of dielectric constant(or relative permittivity) 3. Find the ratio of the total electrostatic energy stored in both capacitors before and after the introduction of the dielectric.
