Answer to Question #199091 in Field Theory for Mallory

Question #199091

Two equally charged objects of mass 1.68 kg are located 0.08 m apart. Determine the possible charges on the objects if the net force on each of them is zero.

Expert's answer

k\frac{q^2}{r^2}=G\frac{m^2}{r^2}\\(9\cdot10^9)q^2=(6.67\cdot10^{-11})1.68^2\\q=1.45\cdot10^{-10}\ C
