Question 22 On the square plates of an air-filled parallel-plate capacitor, equal but opposite charges Q are arranged. The plates are then pulled apart to double their initial separation, which is small compared to the dimensions of the plates. Which of the claims concerning this capacitor is correct? (There may be several right answers.) The capacitance has doubled. The energy density in the capacitor has increased. The potential difference across the plates has doubled. The energy stored in the capacitor has doubled. The electric field between the plates has increased.

Dielectric Constant Of Water
Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.
Electrostatic Potential and Capacitance
An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particles. The electric force is the force which acts between two stationary charges. It is also called Coulomb force.
