can you move a charge in an electric field without work done and how?

If there is a path in electric field that has same potential at all points of the path, then if we move the charge through this path,  we do not have any workdone for this movement of charge.
For example, if we have a collection of charges concentrated at a given point P, then the electric field is radially symmetric. If we consider a circular path with centre as point P, then all the points in this path has same potential. If we move a test charge along this circular path, no work is required for the movement of charge. hence workdone is zero.

CBSE 12-science - Physics
The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
