Coulomb's Law

Elaborate Coulomb’s Law

Electrostatically charged objects exert a force upon one another; the magnitude of this force can be calculated using Coulomb’s Law

What are the two types of charges and what does this mean in terms of what they are deficient of? What repels? What attracts?

There are only two types of charges: positive and negative. Positively charged objects have a deficiency of electrons and vice versa. Like charges repel, unlike charges attract.

Can you explain the relationships for the Coulomb’s Law expression?

Force is proportional to the product of the two point charges. Force is inversely proportional to the distance squared between the charges

What attracts neutral conductors?

Positively and negatively charged objects induce attraction due to their electric fields, causing the redistribution of charges within the neutral conductor.

What happens with you rub a ruler with a cloth?

You can acquire static charge through friction. When the ruler is rubbed with the cloth, the cloth pulls some electrons from atoms on the surface of the ruler. This leaves the ruler with less electrons than protons (positive) and the clothe with excess electrons (negative).
