Acapacitor 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 for your .
