The inner and outer radii of a spherical vacuum-filled capacitor are 4.00[mm] and 6.00[mm], respectively. Positively charged is the inner spherical shell, whereas negatively charged is the outer shell. What is the electric energy density at r=5.00[mm] from the center of the inner sphere if the potential difference across the conducting shells is 4.50[V]? A. 0.156 x 10-4 [J/m³] B. 2.06 x 10-5 [J/m³] C. 5.16 x 10-1⁰ J/m³] D. 9.56 x 10 ⁹ J/m³]

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.
