Consider an infinite number of identical particles, each with charge q, placed along the x axis at distances a, 2a, 3a, 4a,. . . from the origin. What is the electric field at the origin due to this distribution

E = (9×10⁹/a²) × (1+1/4+1/9+1/16+...+1/n²)

Explanation:

See the attachment below.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
