why does a positive charge produce high potential near it while a negative produces low potential near it?

Potential at a point is related to the net sign of collection of charges that produces the electric field. 
By definition, potential at a point is defined as the workdone on a test charge for bringing it from infinite ditance to that point in electric field.
test charge is always considered as positive. Hence the net sign of collection of charges is +ve, potential at apoint is positive.
If the net sign of collection of charges is -ve, potential at a point is negative.

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?
