A capacitor is formed from two concentric spherical conducting shells separated by vacuum. The inner sphere has radius 12.0 cm ,
and the outer sphere has radius 14.0 cm . A potential difference of 100 V is applied to the capacitor. A)What is the energy density at r= 12.1 cm , just outside the inner sphere?
B)What is the energy density at r = 13.9 cm , just inside the outer sphere?
C)For a parallel-plate capacitor the energy density is uniform in the region between the plates, except near the edges of the plates. Is this also true for a spherical capacitor?
There are formulas related to energy density but i couldn't figure out the solution.I would be thankful for your helps.
