In the rectangle of the figure the sides have lengths \( 6.15 \mathrm{~cm} \) and \( 17.1 \mathrm{~cm}, q_{1}=-4.81 \mu \mathrm{C} \), and \( q_{2}=+1.83 \mu \mathrm{C} \). With \( \mathrm{V}=0 \) at infinity, what is the electric potential at (a) corner A and (b) corner B? (c) How much work is required to move a charge \( q_{3}=+2.79 \mu \mathrm{C} \) from B to \( \mathrm{A} \) along a diagonal of the rectangle? (d) Does this work increase or decrease the electric potential energy of the three-charge system? Is more, less, or the same work required if q3 is moved along a path that is (e) inside the rectangle but not on a diagonal and (f) outside the rectangle? (a) Units (b) Units
