two point charge q1q2>0andq1q2<0what is the nature of force between them?  
Asked by jaatkaboy | 08 May, 2019, 08:21: AM
answered-by-expert Expert Answer
If two charges q1 and q2 are such that q1q2 > 0 , then either both are +ve charges or both are -ve charges.
Hence repulsive force is there between similar charges q1 and q2 .
 
If two charges q1 and q2 are such that q1q2 < 0 , then one of them has  +ve charge and other one has -ve charge.
Hence attractive force is there between opoosite charges q1 and q2 .

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?
