Question

1. explain electrostatic charge regarding attraction and repulsion.
2. who determined an equation to explain how particles behaved?

Explanation:

1. Electrostatic Charge (Attraction and Repulsion):

• Objects can have positive, negative, or no (neutral) charge.
• Opposite charges (e.g., positive and negative) attract each other.
• Like charges (e.g., positive and positive, or negative and negative) repel each other.
• This is due to the electric force between charged particles. For example, electrons (negative charge) are attracted to protons (positive charge) in an atom, and two electrons will repel each other.

1. Equation for Particle Behavior:

• Coulomb determined Coulomb's Law.
• Coulomb's Law (\(F = k\frac{q_1q_2}{r^{2}}\)) describes the magnitude of the electrostatic force (\(F\)) between two point - charges (\(q_1\) and \(q_2\)) separated by a distance (\(r\)). Here, \(k\) is the Coulomb's constant. It explains how charged particles (which can be considered as point - charges in some cases) interact in terms of attraction or repulsion based on their charges and the distance between them.

Answer:

1. Opposite charges attract, like charges repel.
2. Coulomb (with Coulomb's Law).
