Point charge A is on the a-axis at a = -3.00 cm. At a = 1.00 cm on the a-axis its electric field is 2100 N/C. Point charge B is also on the a-axis, at a = 5.00 cm. The absolute magnitude of charge B is twice that of A. Find the magnitude and direction of the total electric field at the origin if both A and B are positive.

Question
Point charge A is on the a-axis at a = -3.00 cm. At
r = 1.00 cm on the x-axis its electric field is
2100 N/C. Point charge B is also on the r-axis,
at a = 5.00 cm. The absolute magnitude of
charge B is twice that of A
Find the magnitude and direction of the total electric field at the origin if both A and B are positive.
Express your answer in newtons per coulomb. Enter positive value if the field points in +x-direction and
negative value if the field points in -a-direction.
