Question

According to Coulomb's law, rank the interactions between charged particles from lowest potential energy to highest potential energy. a. a 1+ charge and a 1- charge separated by 100 pm b. a 2+ charge and a 1- charge separated by 100 pm c. a 1+ charge and a 1+ charge separated by 100 pm d. a 1+ charge and a 1- charge separated by 200 pm

Accepted Answer

Understand Coulomb's Law: Coulomb's law states that the force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them. The formula is given by F = k \frac{$$q_1$$ $$q_2$$}{$$r^2$$}, where F is the force, $$q_1$$ and $$q_2$$ are the charges, r is the distance between the charges, and k is Coulomb's constant.. Identify the nature of the charges: Charges can be positive (+) or negative (-). Attractive forces (resulting in lower potential energy) occur between opposite charges, while repulsive forces (resulting in higher potential energy) occur between like charges.. Consider the magnitude of the charges: The greater the magnitude of the product of the two charges (|$$q_1$$ * $$q_2$$|), the stronger the interaction (whether attractive or repulsive), and thus the greater the magnitude of potential energy.. Consider the distance between charges: The potential energy is also inversely proportional to the distance between the charges. A smaller distance means higher potential energy for repulsive interactions and lower potential energy for attractive interactions.. Rank the interactions: Use the information about the nature, magnitude of charges, and distance to rank the interactions from lowest to highest potential energy. Remember that attractive interactions generally have lower potential energy compared to repulsive interactions at the same distance.
