The answer to “Can charging an Object Alter its weight ?” is “Yeah”. To charge electrically something that has, when is electrically neutral, weight W, it is necessary to make some external work at placing, say, electrons, into the something, at impacting on the electrons to overcome the repulsive electric force. At that the system “the something + electrons” obtains corresponding portion of energy ∆E,and so the something’s inertial and gravitational masses increase on ∆m=∆E/c2.

Correspondingly the system has increased on ∆W=∆mg weight.

Of course it can wnd does. Charging an object means adding electric charges, that the object doesn't already possess, to the object, making a bound state of the object and the charges. The charges themselves possess mass, therefore weight.

As that rigorously scientifically rationally shown in Shevchenko-Tokarevsky’s Planck scale informational physical model, in this case see section 6.“Mediation of the fundamental forces” in

- any of at least fundamental Nature Gravity, Electric, and Nuclear/Strong forces charges, and the Forces mediators [so the Forces fields in classic/macro physics] , by no means contain energy – that evidently violates the energy conservation law; and so both – the charges and mediators -don’t have both – inertial and gravitational masses.

Only particles and systems of particles have fundamentally obligatorily inertial masses, m, and so corresponding energies E=mc2, as that was proposed by Einstein in 1905 in the paper “Does the inertia of a body depend on its energy content?”: inertia of a body depends only on its energy content independently on anything, including on in those times known Electric Force properties and effects - what was in contrast to other physicists that proposed a number of “electromagnetic masses”, etc.

At interactions of charged material objects [particles, bodies, etc.] that have, if are at rest in the absolute 3D XYZ space of Matter’s fundamentally absolute, fundamentally flat, fundamentally continuous, and fundamentally “Cartesian”, spacetime that has utmost universal metrics [5]4D (cτ,X,Y,Z,ct), inertial masses, m0, and energies E0=m0c2,

- in closed systems happen only as re-distribution of the sum of the elements’ energies. That can be violated only at external impacts. Say, if an electron it attracted by a proton, firstly the systems energy/mass is E=me0c2+mp0c2, but for/by “external” in this case reason/way when electron occurs on the H-atom S-orbital, this system radiates 13.6eV photon, and the created H-atom inertial mass is lesser than the the sum of the particles above rest masses on the “electrical mass defect” ∆m=13.6eV/c2.

That happens if forces in a system are attractive, and so the system of elements is stable. If forces between elements are repulsive, a stable system can be formed only by spending external energy portion, ∆E, that is spent for the system forming, remains be stored in the system, while the system’s mass – i.e. really the elements masses - is/are larger than the sum of free elements masses on ∆E/c2.
