Homework Help: Force and Charges

  1. Apr 30, 2014 #1
    1. The problem statement, all variables and given/known data

    What will be the force between two charges if the magnitude of the charges and the distance between them are reduced by 50%

    2. Relevant equations

    F= [(k)(Q1)(Q2)]/(r^2)

    3. The attempt at a solution
    Is it that the charge would be 1/2C then 1/2d, then solve for F

    Replace Q1 by Q1/2, r by r/2, etc. Then see how the force changes.
