begin mathsize 12px style Hi space Aashu comma The space electrostatic space force space is straight F equals straight k fraction numerator straight q subscript 1 straight q subscript 2 over denominator straight r squared end fraction equals 9 cross times 10 to the power of 9 cross times open parentheses 1.6 cross times 10 to the power of negative 19 end exponent close parentheses squared over open parentheses 20 cross times 10 to the power of negative 2 end exponent close parentheses squared therefore straight F equals 5.76 cross times 10 to the power of negative 27 end exponent space straight N end style

CBSE 12-science - Physics
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?
