The problem involves a point charge being moved inside a hollow charged cylinder, with specific initial and final positions defined. The central question is about the work done by the electric force during this movement.
The discussion is exploring the nature of the charged object (cylinder vs. sphere) and whether it is a conductor or an insulator. Some participants have provided clarifying questions and assumptions about the charge distribution, while others have expressed agreement on the potential being constant inside a uniformly charged cylinder.
There is a lack of specific information regarding the charge density and the type of charge distribution in the cylinder, which is relevant to the discussion of electric potential and work done.
Hello cesaravila. Welcome to PF !cesaravila said:Homework Statement
A point charge q is moved inside a hollow charged cylinder of radius R. The initial point A is a distance (3/4)R from the center and the final point B is at the center of the sphere. How much work is done by the electric force in this case?
2. The attempt at a solution
I am thinking that no work is done because its equipotential, but I am not certain its equipotential.

In one place you mention a cylinder. In another you mention a sphere.
Which is it ?
haruspex said:Is the cylinder a conductor? A uniformly charged non-conductor? Any mention of the charge or charge density?
Assuming it is a uniform charge and a long cylinder, I agree the potential should be constant inside.cesaravila said:It is a charged insulator.
