electrostatics
The fact that the power supply and one plate of the capacitor are earth grounded at different locations simply potentially introduces additional resistance through which charging occurs. That resistance increases the charging time constant (t=RC) slowing down the rate of charging the capacitor.

Why does a capacitor plate connected to Earth lose charge?
Hence the charges on the outer surface of both plates is 0. Now the charge on the inner plate of the left plate has to be Q1 as its net charge is Q1 and it cannot lose or gain charge as it is not earthed. But the right plate can gain or lose any charge, the only condition is that the outer plate has to have 0 charge.

When solving "floating" circuits you need to remember that every conductor has self capacitance and is therefore connected to ground. Usually, the self capacitance is so small that it can be neglected, but in a question like this it becomes important.
Grounding system of conducting plates
So, the result is: whenever you ground one of the plates (any of them!), the total charge of all the plates becomes zero. After that it''s obvious why the charge of outermost surfaces is zero: electric field outside the system of plates is zero, the electric field inside any plate (including outermost ones) is zero, so the charge on outermost ...
The Parallel-Plate Capacitor
oppositely, is called a parallel-plate capacitor. • Capacitors play important roles in many electric circuits. The electric field inside a capacitor is where A is the surface area of each electrode. Outside the capacitor plates, where E+ and E– have equal magnitudes but opposite directions, the electric field is zero. The Parallel-Plate ...

Charge on surfaces of capacitor when one plate grounded
When one plate of the capacitor is grounded, it effectively becomes neutral, so the charge on that plate becomes zero. If the other plate initially had a charge ( Q ), then after grounding one plate, the charge on the other plate will also be ( Q ) to maintain overall charge neutrality in the system.
How does a capacitor ''transfer'' voltage/charge from one plate to …
$begingroup$ @Charles34 If you place a positively charged conductor near a neutral conductor, something happens to the charge in the neutral conductor.

Is electric potential of the grounded conductor of a capacitor always zero?
Zero potential is whatever you choose it to be. And the meaning of "grounded" can be nebulous (no pun intended). For example, "grounded" could mean the negative terminal of the capacitor is connected to the earth.

Role of ground in charging a parallel plate capacitor
The ground has a significant impact on the charging of a parallel plate capacitor. When one plate is connected to the ground, it provides a pathway for the electrons to flow and create a charge imbalance. This allows for the capacitor to be charged to its maximum capacity and store more energy. 3. Can a parallel plate capacitor be …
