Two point charges, q1 and q2, are placed 0.30 m apart on the xaxis, as shown in the figure above. Charge q1 has a value of –3.0 x 10–9 C. The net electric field at point P is zero
Q: Calculate the magnitude of charge q2.
Q: Calculate the magnitude of the electric force on q2 and indicate its direction.
Q:Determine the xcoordinate of the point on the line between the two charges at which the electric potential is zero.
Q:How much work must be done by an external force to bring an electron from infinity to the point at which the electric potential is zero? Explain your reasoning.
