An annular ring with a uniform surface charge density o sits in the xy plane, with its center at the origin of the coordinate axes. The annulus has an inner radius ry and outer radius 72. (Figure 1) Figure 1 of 2 > VT Y Part B By exploiting the above symmetry, or otherwise, calculate the electric potential Vat a point on the axis of the annulus a distance d from its center. Be sure to visualize this carefully; the point we are interested in lies along the axis of the annulus, but is above the plane of the annulus by a distance d Express your answer in terms of some or all of the variables o, r?, 2, and d.
