The work done by an electric force in moving a charge from point A to point B is 2.76 10-3 J. The electric potential difference between the two points is VA − VB = 47.5 V. What is the charge

  • physics -

    charge * (potential diffence) = (potential energy difference) = Work

    charge = 2.76*10^-3 J/47.5 J/C

    The answer will be in Coulombs.

    Remember that 1 Volt = 1 Joule/Coulomb
