Electric Field Tension In Wire Problem HELP

[NickPA]

Problem Statement:

Attached in pic. Find the tension between the wire of two charges.

My attempt: So basically idk how to account for tension and thought you can just use the E-Force between the two charges in the direction towards the E-Field. How do i account for the tension? In which direction should the tension force point?


Thanks

Try drawing a free body diagram for the negative charge. What forces are going to be acting on it? The tension is the force in the wire, which transmits a mechanic force between the positive and negative charges (in addition to the electric force which is due to the electric field).
