Electric Potential and Four Point Charges
Four point charges q = +3.6 uC are arranged in a square of edge length 2.0 cm. What is the electric potential at the center of the square? What is the electric potential at the midpoint of one edge?
Electrical potential U is equal to
U = SUM (1/(4pi(e_0)) * (q_i)/(r_i)
where q_i are the charges that contribute to U and r_i are ...
This solution provides calculations and answers for (a) the electric potential at the center and (b) the electric potential of the middle of each side.
