Two large parallel sheets of charge are separated by a distance d , small compared to the size of the sheets. The distance d is small enough that the sheets can be treated as if they were infinite in extent. The charge per unit area on the sheets are +σ and -σ respectively. For this problem, we are considering the electric field and potential along the coordinate line x shown. The 0 of the coordinate is at the left sheet. A. Select which graphs below could be appropriate as a graph of each of the following quantities as a function of x . If more than one answer works, give them all. If none works, write N. (a) The electric field Explain your reasoning. |
B. If the distance between the sheets is halved, does either the potential or the electric field between the sheets change? Explain.
