In the figure below, equipotential lines are shown at 1-m intervals. Suppose that V1 = 4 V, V2 = 8 V, V3 = 12 V, V4 = 16 V, and V5 = 20 V. 1)What is the electric field at point A? Enter a positive value if the electric field points in the +x direction and a negative value if if the electric field points in the -x direction. (Express your answer to two significant figures.) 2)What is the electric field at point B? Enter a positive value if the electric field points in the +x direction and a negative value if if the electric field points in the -x direction. (Express your answer to two significant figures.)
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.
