Homework Help: Electrostatic and gravitational force

  1. Sep 1, 2015 #1
    1. The problem statement, all variables and given/known data
    Point charge Q = 4.26 μC is fixed at the origin. Now, point charge q = 4.88 μC is carefully placed directly above it (along the y-axis), and it floats at (0,9.51 cm). Find the mass of q, in kg. Assume: g = 9.803 m/s^2.

    2. Relevant equations
    3. The attempt at a solution
    I guess I need to figure out the relationship between electrostatic and gravitational force.
    but will it be as simply as F=G?
