Two 1.60-cm-diameter disks spaced 1.80 mm apart form a parallel-plate capacitor. The electric field between the disks is 5.20×105 V/m . A) What is the voltage across the capacitor? B) An electron is launched from the negative plate. It strikes the positive plate at a speed of 2.10×107 m/s . What was the electron's speed as it left the negative plate?
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.
