Is the Energy We use for charging a neutral body equal to the electric potential energy gained by a nearby charged body?

The neutral body could be a Van de Graff generator. If its not equal it brings problems.This link holds more detail https://www.researchgate.net/publication/308595788_CREATE_ENERGY_ELECTROSTATICS.

Will light from a given source reach a more massive Body quicker than to a less massive Body due to it's strong gravity?

A more massive body will apply a stronger pull on a photon than a less massive body. Is this correct?

What will be my time dilation compared to Earth when I enter the event horizon of a Black hole and fall towards the singularity at light speed?

We all agree that time stops in a Black hole compared to most parts of space, now what if in addition to that I move at the speed of light in it. Will I go back in time?

Do atoms of White and coloured bodies contain more energy than atoms of Black bodies?

White and coloured bodies have enough energy so reflect out excess while Black bodies have low energy and so have enough room to absorb all and reflect no light. Is my hypothesis correct?

Will a Satellite stay longer in orbit if We placed it in an orbit exactly above the high tide?

There is a chance that since the moon's gravity is strongest at that point this will minimize the orbital decay. The satellite could also be placed to periodically pass through the high tide to...

Non ferromagnetic materials have all their Electrons paired, will adding Electrons to them or basically charging them make them ferromagnetic?

Basically I mean that will a negatively charged body make a better magnet, since unpaired electrons are the source of magnetism in ferromagnetic materials. So after negatively charging a material...
