This figure shows the equipotential lines of a charge distribution, each of which are 5 Volts apart. In inner equipotential has the highest voltage. What direction does the electric field have at point A? O East O West O North O South Submit Answer Tries 0/2 How much work is needed to move a charge of 9 mC from position A to position E? 5 m) -5 m) O 90 m) -90 mJ
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.
Electric field is directed perpendicular to equipotential line. Moreover, electric field is directed in the direction of decreasing potential. Therefore, electric field at point A is towards West.
