A parallel plate capacitor is located horizontally such that one of the plates is submerged in a liquid while the
other is above the liquid surface. When plates are charged the level of liquid
rises
falls
remains unchanged
may rise or fall depending on the of charge amount

The molecules of liquid will convert into induced dipole, get oriented along the electric field produced between the plates and rise due to force of attraction.
Two vertical metallic plates carrying equal and opposite charges are kept parallel to each other like a parallel plate capacitor. A small spherical metallic ball is suspended by a long insulated thread such that it hangs freely in the centre of the two metallic plates. The ball, which is uncharged, is taken slowly towards the positively charged plate and is made to touch that plate. Then the ball will
stick to the positively charged plate
come back to its original position and will remain there
oscillate between the two plates tauching each plate in turn
oscillate between the two plates without touch them
The ball on touching plate A will get positively charged. It will be repelled by and get attracted towards B. After touching B it will get negatively charged. It will now be repelled by and get attracted towards A.
Thus it will remain oscillating and at the extreme position touch the plates.
