Aspherical object consists of an inner sphere of radius a, and a concentric outer conducting shell. the inner sphere has a charge density p(r) = p. x where po is a positive constant, and r is the distance from the center of the sphere. the conducting shell has an inner radius b and outer radius c. the net charge of the shell is zero. (a) calculate the electric field everywhere. (6) assuming v = 0 at the infinite far, calculate the electric potential everywhere (c) if the inner sphere is also conducting, calculate the capacitance between two conductors.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
