Force = q×E = 5×10-12×4 = 20×10-12 N
 
acceleration = Force / Mass = 20×10-12 / 2000 = 10-10 M/s2
 
Distance travelled in 3 s starting from rest = (1/2)×a×t2 = (1/2)×10-10×9 = 4.5×10-10 m

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?
