Problem

Two very large flat parallel sheets are separated by

10.0\,\mathrm{mm}

of vacuum. One carries a uniform surface charge density

+2.4\times10^{-7}\,\mathrm{C\,m^{-2}}

, the other

-2.4\times10^{-7}\,\mathrm{C\,m^{-2}}

. Treat the sheets as infinite planes of charge and ignore edge effects. ((a)) Find the magnitude of the electric field at a point midway between the sheets,

5.0\,\mathrm{mm}

from each. ((b)) Find the magnitude of the electric field at a point between the sheets but only

0.50\,\mathrm{mm}

from the positive sheet. ((c)) Find the magnitude of the electric field at a point just outside the pair,

2.0\,\mathrm{mm}

beyond the negative sheet.
