A nervous physicist worries that the two metal shelves of his wood frame bookcase might obtain a high voltage if charged by static electricity, perhaps produced by friction.   (a)What is the capacitance (in F) of the empty shelves if they have area 3.00 ✕ 10−1 m2 and are 0.300 m apart? F   (b) What is the voltage between them (in V) if opposite charges of magnitude 2.10 nC are placed on them? V   (c) To show that this voltage poses a small hazard, calculate the energy stored (in J).J

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.
