Point Charge Electric Potentials and Fields 1. An uneven dipole centered on the origin as drawn. The (0,y) separation between the charges is d. The leftmost charge (+3q) is positive and three times as large as the rightmost charge (-q), which is negative. Express all answers in terms of the constants k, q, and d. a. (Review) Find the y-component of the electric field +3q as a function of y at the location (0,y). b. Find an algebraic expression for the electric potential at location (0,y). This is the electric potential (voltage) as a function of y, V(y), anywhere the y-axis. c. Show that your electric potential satisfies: E IV y d. (Extra Credit) Why can't we find the other electric field component using our electric ptential function and E =- 7 What information are we missing? X dx
