C) Find the potential at C.

In the diagram, q1 is 9.60 nC, q2 is 1.40 nC, q3 is 2.00 nC, and q4 is 1.90 nC. The distance d is 9.30 mm. Find the potential at point A in the diagram, at the center of the square. Assume that V = 0 at infinity. Find the potential at B. Find the potential at C.

Explanation / Answer

A) r = sqrt(2)*d/2 = 6.576*10^-3 m

Vnet = V1+V2+V2+V3 = k*(q1/r + q2/r + q3/r + q4/r) = 2.04*10^4 volts

B) Vnet = V1+V2+V2+V3 = k*(q1/2*d + q2/d + q3/sqrt(5)*d + q4/sqrt(2)*d) = 8.16*10^3 volts

c)Vnet = V1+V2+V2+V3 = k*(q1/(sqrt(2)*2*d) + q2/(sqrt(3)*d) + q3/sqrt(5)*d + q4/sqrt(2)*d) = 6.23*10^3 volts
