Coulombs law and particle charges

Click For Summary
SUMMARY

The discussion focuses on calculating the charge of a particle using Coulomb's Law, given an attractive force of 0.0096 N between an electron and the unknown particle at a distance of 0.001 m. The known charge of the electron is -1.602E-19 C. Participants emphasize the importance of applying the mathematical form of Coulomb's Law, which states that the force (F) between two charges (q1 and q2) is proportional to the product of the charges and inversely proportional to the square of the distance (r) between them. By rearranging the equation and substituting the known values, the charge of the other particle can be determined.

PREREQUISITES

What do you think, what kind of force is working between the two charges ?

You yourself have said about the law, just find out its mathematical form and then you can solve it easily.

1. Write out (symbolically) the relevant equation (This should appear in the Relevant Equations portion of your post).
2. Solve (algebra) for desired unknown.
3. Replace the known variables with their given numerical values
4. Crunch the numbers to arrive at the result.
