Dear Tutors,

Please help me with the following problem and include steps. Thanks!

Problem 5. (15 points) The x-axis is the axis of symmetry of a stationary uniformly charged ring of radius "R" and charge -Q as the figure shows. An electron of mass m and charge q is located initially at the center of the ring. When the electron is displaced slightly so its initial speed is approximately zero, it accelerates along the x-axis toward infinity. What is the speed of the electron when it passes the point x = R? {Express your answer in terms of the given quantities}.
