Electric potential is a scalar which means you merely add up all the potentials at the center of the cube while ignoring the direction it is pointed in. I supposed voltage (or electric potential) could be 0 if you have an even number of positive and negative charges all with the same distance from the center (if the charges are on the corners of the square the distances would in fact be the same).
No
It is not possible to draw a cube with a continuous line that draws each edge only once.
yes... if it is just sitting there, it has potential energy..... if it is falling into a glass, it has kinetic energy
Absolutely ! A 1 metre cube of steel, and a 1 metre cube of wood both have the same volume - but are obviously different densities.
A cube of platinum of the same size as a cube of silver will weigh more.
If the cube is uniform ( ie it has uniform density) then the geometric center of the cube is its center of gravity.
Not possible. A cube has 12 edges.
1.
There are three kinds of symmetries for a cube: planes of symmetry, lines of symmetry and a center of symmetry.A cube has:9 planes of symmetry13 lines of symmetry1 center of symmetry (at the center of the cube)
No
In Center
Yes, it is possible.
