Electrostatric force on a test charge is stronger when it's closer to another charge.
In exactly the same way, mathematically, that the gravitational force on a test mass
is stronger when it's closer to another mass.
And in exactly the same ratio.

To charge it positively placed a negatively charge body near it. The positive charge of the sphere is attracted near to the surface close to the negatively charge body. To make it completely positive just earth it (by touching it). This process is known as induction. To charge a body negatively is similar to the aforementioned method.
no they will not
Actually Coulombs law is applicable only for point charges but not for bodies. But while calculating the electrostatic force between two spherical charged bodies they supposed as point masses(objects) but the distance seperation should be more greater than their radii. Otherwise the charge on one body can influence charge on another body.

The electrostatic repulsion.
The electrons in one atom and the protons in the other attract each other, and vice versa. When the two atoms are close enough, the electron orbitals merge, forming a hybrid orbital, and the two atoms 'share' electrons---resulting in an even stronger, covalent, bond. Atoms held together because one has a net positive charge and the other a net negative charge form an ionic bond.

no they are not
it will be a close tie
According to Coulomb's Law, the force between two charged particles is directly proportional to the product of the charges and inversely proportional to the square of the distance between the centres of the charges... where the charges are modelled as a particle.F = kQq/r2k = (4 x pi x [epsilon-nought (i.e. the permittivity of free space)])Q = the charge on an objectq= the charge on the other objectr= the distance between the centres of the charges.It drops with square of the distance.The force varies inversely as the square of the distance.Basically, the further away the objects are, the weaker the charge is going to be. If the objects are close, the charge will be stronger.
No. Not even close.
not even close..
They benefit from the thermal winds....close to land during the day winds are stronger away from coast you get stronger sea breezes
an electrostatic precipitator is a device in which a dusty air stream is passed through some plates carrying a high voltage. This adds an electric charge to the dust particles. When the air stream then passes close to some plates that are grounded, then the charges attract the dust to the plates, and the dust is captured for disposal.Some furnace processes create a lot of fly ash, and the above device is typically used to capture the dust.
