Thread: How do charge create it's static electric field ?

a mass of an object create a Gravity field around it because the mass bend the space time around it . so how about charge ? How do it create a static electric field ? Is it bend space time too?

Mass generates a gravitational field which may or may nor have a curved spacetime. Einstein never said that gravity was a curvature in spacetime for that reason. In fact he said that one can "produce" a gravitational field merely by changing your system of coordinates from any inertial one to a non-inertial one.

No.

I don't think the QT 3D-interpretation is valid/useful for infinite range (or even small macro) phenomena.
Black hole have charge, I don't think any photon (virtual or not) will be exchanged with such a object, which anyway "create" an electric field.

A fine question. I would say it is bend electric field (bend in a nice square law way)

I am not even sure that EF and gravity interact with each others. I only know that disturbance in them (photon/matter) do.

Charge cannot exist without matter, but matter can exist without charge. So EF is kind of secondary to Spacetime.
