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.

Question

**Where is the Potential Zero?**

Two point charges are fixed in place. The positive charge is \( +2q \) and the negative charge is \( -q \). On the line that passes through the charges, how many places are there at which the total potential is zero?

---

**Explanation of Diagram:**

The provided diagram shows two point charges placed on a straight line. The line has three labeled points, \( P_1 \), \( P_2 \), and \( P_3 \), which represent specific locations along the line.

- \( P_1 \) is a point near the positive charge \( +2q \).
- \( P_2 \) is a point between the positive charge \( +2q \) and the negative charge \( -q \).
- \( P_3 \) is a point near the negative charge \( -q \).

Both charges, \( +2q \) and \( -q \), are positioned along this horizontal line, with the illustration suggesting the spatial relationship between them. The goal is to identify the locations along this line (points \( P_1 \), \( P_2 \), and \( P_3 \)) where the electric potential is zero.
