Find electric field separating two charged masses suspended on strings

AI Thread Summary
The discussion focuses on finding the electric field between two charged masses suspended on strings. The original poster struggles with the problem and is asked to show their work to receive assistance, highlighting the importance of understanding the interactions between the charges. It is noted that one charge is positive and the other negative, which affects the forces acting on them. Participants inquire about the relevant equations for the force between charged particles and the direction of these forces. Clarifying these concepts is essential for solving the problem correctly.

I got what you got
 
It would appear that you've not accounted for the interaction between the two charges. One is positive and the other negative, so...
