How Does Coulomb's Law Determine Force in a Charged Square Configuration?

Click For Summary
SUMMARY

The discussion focuses on calculating the electric force on charges arranged in a square configuration, specifically with each corner of a 2.0 cm square holding a charge of -1.0x10^-6 C. Using Coulomb's Law, the net electric force (FeNet) is determined to be 22.5 N. The calculation involves applying the formula Fe=kq1q2/r^2, where k is the electrostatic constant (9x10^9 N m²/C²), and emphasizes the importance of vector direction when considering forces from multiple charges.

Homework Statement


A square with side lengths 2.0 cm has a charge of -1.0x10^-6 at every corner. What is the magnitude and direction of electric force on each charge?


Homework Equations


Fe=kq1q2/r^2


The Attempt at a Solution


FeNet=kq1q2/r^2
=(9x10^9)(-1.0x10^-6)^2/(0.002)^2
=22.5 N

You will need to take into account the direction of the force. Set up some coordinate axes and treat the force from each of the 3 other charges on one charge as a vector. Once you've found one the others should be obvious.
