Electrostatics coulomb's law problem

Click For Summary
SUMMARY

The discussion focuses on applying Coulomb's Law to determine the distances between three point charges when the total distance is 50 cm. The relevant equation is f = Kqq/r², where K is Coulomb's constant. A key concept highlighted is the principle of superposition, which is essential for solving problems involving multiple charges. The initial assumption regarding the uniformity of distances was identified as incorrect, emphasizing the need for clarity in problem statements.

Homework Statement


how to use coulomb's law to find the r value of the three points when the total distance is 50 cm


Homework Equations



f=Kqq/r^2

The Attempt at a Solution



i assumed that is it was uniform and sais r1+r2=r3 but now i think that is wrong

By "three points" do you mean "three charges" ? There is one key concept you must use when dealing with charges, that is the concept of superposition.

We cannot help you without a clear statement of the problem you are trying to solve.
