The electric field on two sides of a thin sheet of charge is shown in the figure. The charge density on the sheet is A. `2epsilon_0`B. `4epsilon_0`C. `10epsilon_0`D. zero |
|
Answer» Correct Answer - B Let `E` be the external field (toward right). The `E-sigma/(2epsilon_0) =8`………….i `E+sigma/(2epsilon_0=12`………..ii Solving these equations we get `sigma=4epsilon_0` |
