Question: What is the potential energy of a system of two point charges q1 and q2 separated by a distance r?

Options:

Correct Answer: k * q1 * q2 / r

Solution:

The potential energy U of a system of two point charges is given by U = k * q1 * q2 / r.

What is the potential energy of a system of two point charges q1 and q2 separated by a distance r?

What is the potential energy of a system of two point charges q1 and q2 separated by a distance r?

Step 1: Understand that potential energy is the energy stored in a system due to the position of the charges.
Step 2: Identify the two point charges in the system, which are q1 and q2.
Step 3: Measure the distance between the two charges, which is represented by r.
Step 4: Recognize that k is a constant called Coulomb's constant, which helps calculate the force between charges.
Step 5: Use the formula for potential energy, which is U = k * q1 * q2 / r.
Step 6: Plug in the values of q1, q2, r, and k into the formula to find the potential energy U.
