-71 E View Policies Current Attempt in Progress Figure (a) shows a circular disk that is uniformly charged. The central z axis is perpendicular to the disk face, with the origin at the disk. Figure (b) gives the magnitude of the electric field along that axis in terms of the maximum magnitude E at the disk surface. The z axis scale is set by z,- 31.0 cm. What is the radius of the disk? 0.5E (cm) Number Units C 0 (6) Ni

View Policies Current Attempt in Progress -> In the figure an electric dipole swings from an initial orientation i (0, - 18.3°) to a final orientation f(0, - 18.3%) in a uniform external electric field E. The electric dipole moment is 1.80 x 1027 C-m; the field magnitude is 3.83 x 10° N/C. What is the change in the dipole's potential energy? Number Units Ă
