← A student says: a negative charge, released from rest in an electric field, always moves to a point of lower potential, because positive charges do. What is wrong?A small dipole produces 48 mV at a point P. Point Q lies in the same direction from the dipole as P, but twice as far from it. How much potential does the dipole produce at Q? →
