Question

Standard physics textbooks generally deal with an idealizedparallel-plate capacitor, where the size of the plates is muchlarger than the separation between the plates, something that isnot true in the situation shown in the simulation. Which of thefollowing are true for the standard textbook situation (let's callthat a capacitor with infinite plates) but are not true in thissimulation? Select all that apply. Ina capacitor with infinite plates the electric field in all threeregions (above the top plate, between the plates, and below thebottom plate) points in the same direction.
Ina capacitor with infinite plates there is no electric field in theregions above the top plate and below the bottom plate.
Ina capacitor with infinite plates changing the voltage across thecapacitor while keeping the separation between the plates constantresults in no change in the electric field between theplates.
Ina capacitor with infinite plates changing the separation betweenthe plates while keeping the voltage across the capacitor constantresults in no change in the electric field between theplates.
Ina capacitor with infinite plates the electric field is maximumalong the plane parallel to, and halfway between, theplates.
Ina capacitor with infinite plates the electric field in the regionbetween the plates is uniform.
Ina capacitor with infinite plates, doubling both the capacitorvoltage and the plate separation results in no change in theelectric field between the plates. Ina capacitor with infinite plates the electric field in all threeregions (above the top plate, between the plates, and below thebottom plate) points in the same direction.

Explanation / Answer

Given : A parallel-plate capacitor is a great way to create auniform field. The field is perfectly uniform only when the platesare infinite in size, but as long as the width of the plates islarge compared to the distance between the plates the field isfairly uniform. In a capacitor withinfinite plates the electric field is maximum along the planeparallel to, and halfway between, the plates.
In a capacitor with infiniteplates the electric field in the region between the plates isuniform.
In a capacitor with infiniteplates, doubling both the capacitor voltage and the plateseparation results in no change in the electric field between theplates. I hope it helps you I hope it helps you
