Multiple Choice
Four point charges are on the rim of a circle of radius 10 cm.The charges are (in μC) +0.50,+1.5,−1.0,−0.50.If the electrical potential at the circle's center due to the +0.5 charge alone is 4.5 × 104 V,what is the total potential at the center due to the four charges combined?
A) 18 × 104 V
B) 4.5 × 104 V
C) zero
D) −4.5 × 104 V
