Calculate the net electric field at point A for the following charge distribution. 

q1 northern most point charge of -5x10^-5

q2 Eastern most point charge of -3.0x10^-5

point a the western most point

point a to q1 is 5.0m

point a to q2 is 5.0m

find the net electric force on charge 1, due to the other charges.

q1= +3.0x10^-5

q2= -5.0x10^-5

q3= -5.0x10^-5

distance between q1 and q2 is 30cm

distance between q1 and q3 is 30cm

Q3 is northern most point, q2 is the eastern most point

q2 is the western most point.
