points Tpler6 23 P028 Points A, B, and C are at the comers of an equilateral triangle of side 7.00 m. Equal positive charges of 9.00 JC are at A and B. (a) What is the potential at point c kv (b) How much work is required to bring a positive charge of 5.00 juC from infinity to point C if the other charges are held fixed?

Potential at point C would be given by;
V=V1+V2
V1=k*q1/r
V2=k*q2/r
Where,
k=9*10^9 N.m^2 per coulomb square
q1=q2=9 *10^-6 Coulomb
r=7 m
so,
V=2*V1
V=2*(9*10^9 N.m^2 per coulomb square)*( 9 *10^-6 Coulomb)/(7 m)
V=23.1427*10^3 Volt
Work required to be done to bring a charge q3 from infinity to point C is given by;
W=q3*V
In the question; q3= 5 *10^-6 C
So,
W=5 *10^-6 C*23.1427*10^3 Volt
W=115.7135*10^-3 Volt
The potential at the midpoint of side AB is given by;
V
