Two point charges, q₁ and q_2, are placed 0.30m apart on the x-axis, as shown in the figure above. Charge q_1 has a value of -3.0z10^-9 C. The net electric
field at point P is zero.
(a) What is the sign of charge q_2?
Positive_Negative
Justify your answer.
(b) Calculate the magnitude of charge q_2.
(c) Calculate the magnitude of the electric force on q_2 and indicate its direction.
(d) Determine the x-coordinate of the point on the line between the two charges at which the electric potential is zero.
