Three point charges are placed on the x-y plane: a +40.0nCcharge at the origin, a -40.0nC charge on the x axis at 10.0cm, anda +100.0nC charge at the point (10.0cm, 9.00cm).

(A) Find the total electric force on the +100.0nC charge due tothe other two.

Please answer in this format: ( ? N)x + ( ? N)y

(B) What is the electric field at the location of the +100.0nCcharge due to the presence of the other two charges?

Please answer in this format: ( ? N/C)x + ( ? N/C)y
