## Xylem 4 years ago A spherical cloud of charge of radius R carries total charge Q. The charge is distributed so that its density is spherically symmetric, i.e. it is a function of the radial distance from the centre of the sphere. Explain why the “charge cloud” is equivalent to a point charge of Q Coulombs at the centre of the sphere.

use gauss' law.

xylem, this is your question? Whew, good luck buddy

that's is hard to me 2

lol its an annoying question i cant figure it out doing my head in

construct a gaussian surface surrounding the charge cloud. Gauss's law demonstrates that the charge enclosed in any surface is equivalent to a point charge.
