Drawings A and B show two examples of electric field lines.
Which (one or more) of the following statements are true?

In both A and B the electric field is the same everywhere. |

As you move from left to right in each case, the electric field becomes stronger. |

The electric field in A is the same everywhere, but it becomes stronger in B as you move from left to right. |

The electric fields in both A and B could be created by negative charges located somewhere on the left and positive charges somewhere on the right. |

Both A and B arise from a single positive point charge located somewhere on the left. |

Consider two infinite plates, both parallel to the xy plane of a
coordinate system. The top plate is at the height z = +5cm and
carries a uniform charge distribution of ?= +3nC/m2. The bottom
plate is at height z = - 5cm and carries a uniform charge
distribution of ?= -3nC/m2. The space between the plates is filled
