In the rectangle shown below, the sides have lengths 5.0 cm and 15.0 cm, q1=-5.0 uC and q2=+2.0 uC. With V=0 at infinity:(a) what’s the electric potential at corner A? (2 pts)(b) what’s the electric potential at corner B? (2 pts)(c) How much work is required to move a charge q3 from B to A along a diagonal of the rectangle? (4 pts)(d) Does this work increase or decrease the electric potential energy of the three-charge system? (2 pts
