Consider two concentric conducting spherical shells of negligible thickness separated by vacuum. One of the shells has a radius of 1 m, while the other has radius of 6 m. The total charge of one of the inner shell is 3 uC, while that of the outer is 9 uC. Their respective total charges are distributed evenly on their surfaces. Determine the total potential energy, in millijoules, stored between the two shells. Use the permittivity of free space as 8.854 × 10-12 F/m.
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.
