Point charge A is on the r-axis at a = -3.00 cm. At x = 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 Bis 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 +r-direction and negative value if the field points in --direction. αν ΑΣφ- N/C Find the magnitude and direction of the total electric field at the origin if both A and B are negative. 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 -x-direction.
