Looking for help, thanks!

Problem 1: Your turn. For the same two charges, find the (formula for the) electric field at any point y, along the y-axis. Then find the force that would be exerted on a charge qr = 1000 JC if q+ = -q- = 100 MC and (A) The test charge sat at x=2 on the x-axis and (B) the test charge sat at y = 2 on the y-axis (using the formula I constructed). (Hint: ATE. = 9 x 109 N m2/C2)
