## anonymous one year ago Two balloons having the same charge of 1.2 × 10-6 coulombs each are kept 5.0 × 10-1 meters apart. What is the magnitude of the repulsive force between them? (k = 9.0 × 109 newton·meter2/coulombs2)

here we have to apply the $$Coulomb$$ law, so the requested force has the subsequent magnitude $$F$$: $F = K\frac{{{Q^2}}}{{{d^2}}}$ where $$Q$$ is the common charge and $$d$$ is the separation distance between the balloons. Of course $$K=9 \cdot 10^9$$
