Calculate the potential at the point P at a distance D=2.07 m from one end of the horizontal rod. Special note: You're going to have to take the difference between the potentials made by the positive and negative rods, which are similar numbers. That means that to get an accurate answer you need to keep more digits than usual while you're doing your calculation. For my answer I got 4.15799E11 V which was wrong
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.
Two rods of equal length L=1.99 m form a symmetric cross. The horizontal rod has a charge of Q=500 C, and the vertical rod has a charge of −Q=−500 C. The charges on both rods are distributed uniformly along their length. Calculate the potential at the point P at a distance D=2.07 m from one end of the horizontal rod. Special note: You're going to have to take the difference between the potentials made by the positive and negative rods, which are similar numbers. That means that to get an accurate answer you need to keep more digits than usual while you're doing your calculation.
