A spherical capacitor is formed from two concentric spherical conducting spheres separated by vacuum. The inner sphere has radius $12.5 \mathrm{cm}$ and the outer sphere has radius $14.8 \mathrm{cm} .$ A potential difference of $120 \mathrm{V}$ is applied to the capacitor. (a) What is the capacitance of the capacitor? (b) What is the magnitude of the electrical field at $r=12.6 \mathrm{cm},$ just outside the inner sphere? (c) What is the magnitude of the electrical field at $r=14.7 \mathrm{cm},$ just inside the outer sphere? (d) For a parallel-plate capacitor the electrical field is uniform in the region between the plates, except near the edges of the plates. Is this also true for a spherical capacitor?
