Question

An electron that is initially $55 \mathrm{cm}$ away from a proton is displaced to another point. If the change in the electrical potential energy as a result of this movement is $2.1 \times 10^{-28} \mathrm{J}$, what is the final distance between the electron and the proton? (See Sample Problem 18A.)

Step 1

Step 1: We know that the change in potential energy is given by the formula: \[\Delta U = U_f - U_i\] where $U_f$ is the final potential energy, $U_i$ is the initial potential energy, and $\Delta U$ is the change in potential energy. Show more…

Key Concepts

Electrostatic Potential Energy

This concept refers to the energy stored in a system due to the positions of charged particles. It quantifies the work needed to assemble a configuration of charges by moving them from infinite separation to a specific arrangement. The potential energy between two point charges is given by a formula that involves the product of the charges and is inversely proportional to their separation distance, making it a central idea in studying interactions at the atomic scale.

Coulomb's Law

Coulomb's Law describes the magnitude of the force between two point charges, stating that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. This law provides the foundational relationship that leads to the derivation of the expression for electrostatic potential energy, thereby linking the concepts of force, work, and potential energy in electrostatics.
