A point charge q is located at the center of a uniform ring having linear charge density λ and radius a, as shown in the figure below. Determine the total electric flux through a sphere centered at the point charge and having radius R, where R < a. (Use the following as necessary: q and ε0.) (i) Φ = If q = 2×10−6 C, R = 3 m and a = 5 m, calculate the total electric flux. N⋅m2/C
