SUMMARY
The electric potential at the center of a circle with a radius of 5 cm, formed by a wire with a charge density of λ = 0.1 C/m, is calculated using the formula V = Q/(4πε₀r). The total charge Q can be determined by Q = 2πrλ, leading to the conclusion that the radius does not affect the potential at the center due to the symmetry of the charge distribution. The integration of the electric field from the center to infinity is an alternative method to derive the same result.
