Four point charges are positioned on the rim of a circle. The charge on each of the four is _0.5 mC, _1.5 mC, _1.0 mC, and _0.5 mC. If the electrical potential at the center of the circle due to the _0.5 mC charge alone is 4.5 _ 104 V, what is the total electric potential at the center due to the four charges? (a) 18.0 _ 104 V (b) 4.5 _ 104 V (c) 0 (d) _4.5 _ 104 V (e) 9.0 _ 104 V
