A electric dipole consisting of an electron and proton seprated by a distance of 4m is placed in a uniform electric field intensity 3N/C at an angle 30 with the field. Calculate the dipole moment and torque acting on the dipole.

dipole moment p = q×l = 1.6×10-19×4 = 6.4×10-19 C-m
 
Torque = p×E = p×E×sinθ = 6.4×10-19×3×(1/2) = 9.6×10-19 Nm
 
E is electric field intensity and θ is angle between dipole and electric field

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?
