For this problem,

The solution is,

However, should they be a vertical component of the electric field for the expression circled in red? I do understand that assuming that when the nth charge is added it is placed equal distant for the other charges so that a component of the electric field cancels which would be the y-component from how they defined the coordinate system.

I also note how they could have just used the formula for the E-field produced by a discrete number of charges.

Many thanks!
