- Homework Statement
- Hey, so I've been given this advanced question as part of my physics assignment, and I've been having trouble trying to solve it, so far, I've found multiple answers that all contradict eachother and all of which don't seem right so I'm struggling to find the correct solution. I've attached my current solution below but I still feel this is wrong as the graph doesn't match what I'd expect to happen

The question is as follows:

Derive an expression for the electric field along the vertical line that passes through the negativecharge. How many times does the electric field strength pass through zero? For each such zeropoint of the field, what would happen if a positive test charge was released from rest near to(but not directly on top of) the point where the field is zero?

The question refers to the charge setup below, where one I believe would intuitively expect to find two zero points (One below all the charges, and one above all the charges).
