Set 7 Problem 5 Nonuniformly Charged Ring A flat ring of inner radius R1 = 3.8 cm and outer radius R2 = 6.7 cm carries a nonuniform surface charge density o = are, where r is measured from the center of the ring and a = 0.073 uC/m*. Find the electric potential V at the point on the x axis at x = 5.7 cm. V = V abc sin( x10 Submit Help Reset
