alleryStart learning →A thin infinite plane sheet carries surface charge density sigma. What is the field near it?
Asigma/(e0)
B2 sigma/(e0)
Csigma/(2 e0)
Dsigma/(4 e0)
Answer & Solution
Correct answer: C. sigma/(2 e0)
Gauss law with a pillbox gives 2EA = sigma A/e0, so E = sigma/(2 e0), independent of distance.
