MATLAB roots Problem 3: A total charge Q is uniformly distributed around a ringshaped conductor with radius a. A charge q is located at a distance x from the center of the ring (Fig. 2). The force exerted on the charge by the ring is given by \begin{equation} F = \frac{1}{4\pi\epsilon_0} \frac{qQx}{(x^2 + a^2)^{3/2}} \end{equation} where $\epsilon_0 = 8.9 \times 10^{-12} \text{ C}^2/(\text{N m}^2)$. Find the distance x where the force is 1.25 N if q and Q are $2 \times 10^{-5}$ C for a ring with a radius of 0.85 m. You need to run all codes when possible.

A ring of charge is centered at the origin in the vertical direction. The ring has a charge density of ̷ = 6.93 x 10^-6 C/m and a radius of R = 2.85 cm. Find the total electric field, E, of the ring at the point P = (2.02 m, 0.00 m). The Coulomb force constant is k = 1/(4̷̷₀) = 8.99 x 10^9 N·m²/C². Find the expression for the electric field, E₁, of the ring as the point P becomes very far from the ring (x >> R) in terms of the radius R, the distance x, the total charge on the ring q, and the constant k = 1/(4̷̷₀).
