A point charge with charge q1 = 3.90 μC is held stationary at the origin. A second point charge with charge q2 = -4.40 μC moves from the point ( 0.170 m , 0) to the point ( 0.255 m , 0.270 m ). How much work W is done by the electric force on the moving point charge? Express your answer in joules. Use k = 8.99×109 N⋅m^2/C^2 for Coulomb's constant: k=(1/4πϵ0)
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.
