if u have an uncharged,perfectly conducting hollow sphere of thickness t and radius R, and a point charge Q is placed a distance D from the centre of the sphere so that R-t>D, what would the electric field, E, be?(adsbygoogle = window.adsbygoogle || []).push({});

i just treated it the same as if Q was in the centre of the sphere and the electric field lines came perpendicular to the sphere and so

[tex]E=\frac{Q}{4 \pi \epsilon_{0}D^2} [/tex]

anyone got any better ideas?
