I used the equation E= kqd/(L^3)

L=sqrt(h^2+(d/2)^2)

I got the first answer (for P1).

I can't figure out how to utilize that equation for P2.

The second question asks:

"What is the magnitude of the electric field at

P2? Answer in units of N/C"

what's the value of L (-100... -101.1 or something totally different)... I don't quite understand the variables in the given equation. Help is most appreciated. thx.
