Charge density = 17.7×10-4  / 200 = 0.885 ×10-6 C/m2
 
Electiric field due to charged infinite square plate begin mathsize 12px style equals fraction numerator sigma over denominator 2 epsilon subscript 0 end fraction space equals fraction numerator 0.885 cross times 10 to the power of negative 6 end exponent over denominator 2 cross times 8.85 cross times 10 to the power of negative 12 end exponent end fraction equals 0.5 cross times 10 to the power of 5 space V divided by m end style

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?
