It describes the forces that two small particle-like, charged objects exert on each other, forces that depend on the magnitudes of the charges, qi and q3, as well as the ERROR ANALYSIS: All data should come with an uncertainty reflecting the imprecision of the measurement. Once we started, the apparatus was mostly set up. Step 14: Calculate the total charge ( Q ) on the balloons. Mathematically, the magnitude of this electrostatic force F eacting on two charged particles (q1, q2) is expressed as: Fe= kq1q2 r2 Wherer is the separation distance between the charged objects and k is a constant ofproportionality, called the electric constant (or Coulomb's Constant), k = 8.9876 10 9Nm2/C2.
