ctrostatic paint sprayer has a 0.25 m diameter metal sphere at a potential of 25.0 kV with respect to the ground that repels paint droplets onto a grounded object. Part (a) What charge is on the sphere, in coulombs? Q = Part (b) What charge, in coulombs, must a 0.12 mg drop of paint have in order to arrive at the object with a speed of 10.0 m/s, starting from rest? q =
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.
