Find electric field separating two charged masses suspended on strings

Click For Summary
SUMMARY

The discussion focuses on calculating the electric field between two charged masses suspended on strings, specifically addressing the interaction between a positive and a negative charge. Participants emphasize the importance of accounting for the forces acting on each charge due to their interaction. The key equation referenced is Coulomb's Law, which describes the force between two charged particles. The conversation highlights the necessity of understanding both the magnitude and direction of the forces involved to arrive at the correct solution.

PREREQUISITES
  • Coulomb's Law for electric force calculations
  • Basic understanding of electric fields and forces
  • Vector analysis for determining direction of forces
  • Concept of charge interaction (positive and negative)
NEXT STEPS
  • Study Coulomb's Law in detail, including its mathematical formulation
  • Learn about electric field calculations for point charges
  • Explore vector addition in the context of forces acting on charged particles
  • Investigate the principles of equilibrium in charged systems
USEFUL FOR

Students in physics, educators teaching electromagnetism, and anyone seeking to understand the dynamics of charged particles and electric fields.

Hello jay. By forum rules you'll need to show us exactly what you've tried before we can offer help. We need to see what your current understanding of the problem is.

Can you check it for me what I went wrong ?
This is what I get and it is a wrong answer.

What is the equation for the force between two charged particles? For this problem, in which direction will it act for each particle?
