We have been given the following information: The electric force between the balloons is: $$F = \dfrac{kq_1q_2}{r^2} = \dfrac{(9.00 \times 10^{9}\ \rm{N\cdot m^2/C^2})(-2.0 \times 10^{-6}\ \rm{C})(-2.0 \times 10^{-6}\ \rm{C})}{(0.50\ \rm{m})^2} \approx 0.14\ \rm{N} F = k q1 q2 d2 F = k q 1 q 2 d 2 F F : electrostatic force between the two objects 1 and 2 in newton (N) k : Coulomb constant k 8.987551787368176 109N.m2.C2 k 8.987551787368176 10 9 N. m 2. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. This force is given by the product between the two charges measured in Coulombs, multiplied. As the law works only during certain situations it is not a universal law. The resultant force acting on charge 3 is the algebraic sum of the forces exerted by charges 1 and 2 separately (the sum is algebraic because all the forces act along the -axis). Like charges repel each other; unlike charges attract. After completing his degree, George worked as a postdoctoral researcher at CERN, the world's largest particle physics laboratory.
