SUMMARY

The discussion centers on the placement of a proton in the electric field created by a 2 nC charge at the origin and a -4 nC charge located at x = 1 cm. The user correctly identifies one position between the two charges where the net force on the proton is zero. However, they assert that there is an additional position to the left of the origin where the proton would also experience no net force. This claim is supported by the principles of electrostatics, which dictate that a charge can experience zero net force at multiple points in a field created by two opposite charges.

PREREQUISITES
  • Understanding of Coulomb's Law

Homework Statement


A 2 nC charge is at the origin and a -4nC charge is at x = 1 cm.

a) At what x coordinate is would you place a proton so that it would experience no net force?

Ok I solved for the coordinate in between the two charges, and I got the same answer as my book. However, the book only gives one answer and I think that there should be another place where the force is zero to the left of the origin. Am I correct?
