Question

1) Charge for q2 = 6.00 x 10^-12 C.  Determine the magnitude of the electrical field. Express the answer in N/C form.

2) Using a new value of 7.4 nC for q2, determine the charge needed at point P so that the electric field due to all four charges is zero at point z. Express your answer in nC and include a negative sign if the charge is negative.

Please use what I have provided for the questions.
