Which of the statements regarding this situation are true? Select all that apply.

-In this simulation when the capacitor voltage is set to a positive value the top plate has a positive charge on it and the bottom plate has a negative charge on it.
-In general, decreasing the separation between the plates increases the magnitude of the electric field between the plates.
-Increasing the magnitude of the capacitor voltage while keeping the plate separation constant increases the magnitude of the electric field at all locations (except for locations where the field is zero, which remain at zero).
-Increasing the plate separation while keeping the capacitor voltage constant decreases the magnitude of the electric field at all locations.
-Reversing the sign of the capacitor voltage while keeping the magnitude of the voltage the same reverses the electric field at all locations, but does not change the magnitude of the field.
-Reversing the sign of the capacitor voltage while keeping the magnitude of the voltage the same reverses the vertical component of the electric field at all locations, but does not change the magnitude of the field or the horizontal component of the field at a given location.
