Two protons are released from rest when they are 0.750 $\mathrm{nm}$ apart. (a) What is the maximum speed they will reach? When does this speed occur? (b) What is the maximum acceleration they will achieve? When does this acceleration occur?

Key Concepts

Coulomb's Law

Coulomb’s Law describes the force between two point charges. For like charges, the force is repulsive and varies inversely with the square of the distance between them. This law is key to understanding both the magnitude of the instantaneous force acting on each proton (which determines its acceleration) and how that force decreases as the protons move apart, thereby affecting the acceleration experienced by them.

Conservation of Energy

This principle states that in a closed system, the total energy remains constant over time. In the context of charged particles such as protons, it means that the initial electrostatic potential energy (when the protons are close) is converted into kinetic energy as they repel and move apart. This conversion allows us to determine the maximum speed the protons achieve, as it is reached when nearly all the initial potential energy has been transformed into kinetic energy.
