In the rectangle of the figure the sides have lengths 4.72 cm and 19.3 cm, a-4.24 uC. and a+2.17 uC. With 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,= +3.52uC from B to 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 () outside the rectangle? Units (b) Units (c) Units (d)
