Four point charges are positioned on the rim of a circle. The charge on each of the four (in micro Coulombs) is +0.5, +1.5, -1.0,and -0.5. If we are told that the electrical potential at the center of the circle due to the +0.5 charge is V, what is the potential at the center due to the four charges combined?

The potential V at the centre of the circle due to the 0.5? C
where r is the radius of the circle.
Therefore,
V ' = k [ 0.5 + 1.5 + ( -1.0 ) + (-0.5)]r where r is substituted from equation (1)
