The shield could be left floating, but the shield can be grounded without changing the operation of the circuit since no current will flow in this ground connection since both the shield and the ground are at the same potential. The same is not true of the center conductor.
Terminate shielding at one or both ends? : r/AskElectronics
I watched a video recently that said that shielded cable shielding should be terminated on one end only. People in the comments disagreed and after googling some sources said it should be terminated on both ends to prevent RFI problems and others to terminate the shielding on only one end to prevent ground loops.

More About Grounding And Shielding
It is very important to terminate correctly both ends of the motor cable, otherwise, interference problems may occur. ... If this is not possible then one end of the shielded cable can be terminated via a 100 nF capacitor. This breaks the ground loop at low frequency (50 Hz) while maintaining the shield connection in the high-frequency range. ...
capacitor ground or not?
Regarding your original question about capacitors: "Ground" is an arbitrarily selected reference point that means 0V. ANY point in a circuit could be declared as the 0V "ground" point without affecting how it works. In general, absolute voltages never mean anything - all that matters is the voltage DIFFERENCE between the two terminals of a device.
Cable Shield Grounding
On the matter of how to ground the shields (hardwire to ground, or through a capacitor), and ground currents melting shields, I would like to offer my experience with the care and feeding of ground loops in the shield protecting low- level signals: use a resistor, not a capacitor. ... Grounding both ends of the shield permits high-frequency ...

Shielded CAT6A cable grounding at both ends : r/homelab
It appears the general consensus is to ground at both ends of the cable, but there are also opinions ranging from no grounding to ground at one end only. ... In Ethernet, it makes more sense to use a capacitor, because we only care about frequencies above ~100MHz, so allowing noise in lower bands is acceptable. ...

Terminating cable screens (shields)
The screen at one end of the cable enjoys 360° termination, and when a capacitor is used to terminate the other end it is often called hybrid screen termination. An annular (i.e. ring) capacitor maximises the shielding effectiveness of this technique. 360° terminations360° terminations Low-resistance PEC bonded to equipment at both ends,

$begingroup$ ** Will the electrons move back to V_2 because V_2 is positive and the plate is negatively charged? **<br/></br>The answer is no. The other plate is positively charged. So it will attract the electrons of the negatively charged plate. Moreover, as the positively charged plate has positive electric potential (for its positive charges), it will have influence over …
How to Discharge a Capacitor?
(5) Even if both sides of the capacitor device are grounded, in order to prevent the residual charge on the capacitor, a test discharge must be performed. Each group of capacitors connected in parallel must be discharged. (6) Particular care should be taken when inspecting discharge of capacitors removed due to faults.
USB device cable shield connection
One of the wires inside the cable should be the negative power supply return. Most devices will have the power supply negative and ground connected to the chassi. If both devices are this way and both ends of the shield are connected to ground, then the shield will become a negative power current conductor.

grounding
This works both with and without ground connections to the boxes at each end. You could choose to use conductive BNCs at one end, and insulated at the other (thereby grounding the shield), but once you have a more than two boxes, or if you need to mix-and-match kits, the potential for loops is too high, so the norm is to just use insulated ...

Ethernet Cable Shield Grounding
See Analog Devices, Analog Dialog 17-1, 1983, for one of the most asinine drawn out of rationales. The ultimate insanity is when coaxial signal line shields are grounded at one end only. A cable shield grounded at one end (SPG) behaves like a low pass filter to magnetic fields and a high pass filter to electric fields. A shield it is not.
