Question

Part A Two point charges are located on the y axis as follows: charge q 2.00 Cat y 0.700m, and charge q 4.10 nC at the origin (y E 0). What is the magnitude of the net force exerted by these two charges on a third charge 9.00 nC located at ya 0.300 mn Submit My Answers Give Up Multiple Choice Problem 17.12 Part B A point charge q is separated from another point charge 9.00 q What is the direction of the net force? The net force is in y direction Part A O The net force is in y direction. If the force on q due to 9.00 q is F, then the force on 9.00 q due to q is The net force is in x direction O The net force is in x direction F O 9.00 F Submit My Answers Give Up O 10.0 F O 81.0 F Submit My Answers Give Up

Explanation / Answer

F = q3*E_q2 + q3*E_q1

E_q = kq/r^2, or (1/4*pi*e_0)q/r^2 if you write it like that

remember these are vector quantities

r is the separation distance between charge 3 and charges 1 and 2 (whichever E field you are using). The distance is purely along one direction, so the calculation should be straightforward.
