A capacitor is constructed out of a pair of perfectly aligned rectangular metal plates with a small air gap between them. The capacitor is connected to a 1.5 V battery. Then, without disconnecting the battery, the capacitor is dipped into a beaker of silicon oil so that the rectangular plates become half- submerged in oil. Which of the following quantities stays the same after the capacitor is partially dipped in silicon oil (select all that apply)? The amount of charge in the silicon oil The voltage across the capacitor O The electric field strength in the space between the plates of the capacitor O The total capacitance
