Homework Help Overview

The problem involves two protons aimed at each other with a specified velocity of 1000 km/s, focusing on determining the maximum electrical force they exert on one another. The context is rooted in concepts of kinetic energy and Coulomb's Law.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the relationship between kinetic energy and the electrical force, with one noting the need to find the radius for applying Coulomb's Law. Another participant hints at considering the kinetic energy at minimum separation distance.

Discussion Status

The discussion includes attempts to clarify the role of kinetic energy in the problem and explores whether it has been adequately considered in the solution. There is a suggestion that the problem may have been resolved, but no explicit consensus is reached.

Contextual Notes

Participants are navigating the implications of the given velocity and the relationship between kinetic energy and electrical force, with some uncertainty about the necessary parameters for applying Coulomb's Law.

Homework Statement


The problem states that two protons are aimed at each other with a certain velocity v. It asks what is the maximum electrical force they will exert on each other.
The velocity is given at 1000km/s. And that is everything given.


Homework Equations


KE = 1/2mv^2
F = q*q/(4*pi*e*r^2)

The Attempt at a Solution


I am stuck on the approach. I have managed to find the kinetic energy of the protons but that is it. I don't know where to go from here . I think I should use Coulomb's Law, but I need to find the radius for that. Any suggestions?

Hint: What can you say about the KE of the protons when they reach the minimum separation distance?
 
Great Help! Thank you very much, problem Solved.
 
Just on a hunch, I'll ask if the total kinetic energy of the two protons was included in the problem solution.
