Question

List true or false, and explain why?

The electric potential of the Earth can only be measured relative to some other potential.

A proton, in an electric field, initially at rest, when released will begin to move parallel to the equipotential surfaces.

Equipotential surfaces cross the surface of an electrode.

Electric fields between two parallel plates are uniform in strength except at the edges.

An equipotential surface consists of points at the same potential.

There is no field inside an empty closed hollow charged metal cylinder, and the electric potential inside is therefore zero.

Electric fields all point in the direction of the force on a positive test charge.

No. It is possible to measure the electic field and then to calculate the Earth potential.

No. It begin to move parallel to the electric field.

No. Surface of electrode is equipotential.

Yes.

No. Electric field is week but exist (it is zero in the center only). Potential depends of common charge of the cylinder.

Yes.
