Minimum Work Needed to Bring 2 charges from distance infinity

Click For Summary
SUMMARY

The discussion centers on calculating the minimum work required to bring two charged particles from infinity to a distance of 2 meters. The first particle has a positive charge of 3.0 x 10^-5 C, while the second has a negative charge of 1.35 x 10^-5 C. To solve this problem, one must apply the concept of electric potential energy and the relevant equations that relate force and work. The change in potential energy of the system is critical for determining the minimum work accomplished in this process.

PREREQUISITES

Two charged particles are brought together from a great distance (r=infinity) to a distance of 2 m. The particle has a positive charge of 3.0 x 10^-5 C and the second has a negative charge of 1.35 x 10^-5 C. What minimum work was accomplished in this process?

I can't for the life me figure out how I should set up the equation and solve!
Please help, it's driving me crazy!

What are the Relevant Equations? (that was asked on the Homework Help Template that you deleted when you posted your question...)

What is the equation for the force between two charged particles? What are some equations relating force and work?
 


You should consider the change in potential energy of the system. (And also use the template) I think after filling out the equations part of the template you would have answered the question for yourself.:smile:
