Two protons are separated by a distance R. What will be the speed of each proton when they reach infinity under their mutual repulsion?

Text Solution

AI Generated Solution

To find the speed of each proton when they reach infinity under their mutual repulsion, we can use the concepts of electrostatic potential energy and kinetic energy. Here’s a step-by-step solution: ### Step 1: Understand the initial conditions Two protons are separated by a distance \( R \). Since both protons are positively charged, they will repel each other due to electrostatic force. ### Step 2: Calculate the initial electrostatic potential energy The electrostatic potential energy \( U \) between two point charges is given by the formula: \[ ...
