Question
Part A two point charges are located on the y axis as follows: charge q1 = -1.00nC at y1 = -0.650m , and charge q2 = 3.90nC at the origin (y = 0). What is the magnitude of the net force exerted by these two charges on a third charge q3 = 9.00nC located at y3 = 0.400Part B What is the direction of the net force
the net force is in +y direction
the net force is in -y direction
the net force is in the + x direction
the net force is in the -x directionm Part A two point charges are located on the y axis as follows: charge q1 = -1.00nC at y1 = -0.650m , and charge q2 = 3.90nC at the origin (y = 0).

Explanation / Answer
F = F13 +F23
F = kq1q3/1.05^2 + Kq2q3/0.4^2
F = 9*10^9 *9nC*(-1/1.05^2+3/0.4^2)*10^-9
F =1.445*10^-6 N
b. +y direction
