Let charge +Q is at P which is at a distance d from the mid point of charged rod of length 2l as shown in figure.
Let λ be the linear charge density, i.e. charge per unit length of the rod.
 
Force F experienced by charge Q is the product of charge Q and the electric field E due to the charged rod.

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?
