Two identical 8.60-g metal spheres (small enough to be treated as particles) are hung from separate 300-mm strings attached to the same nail in a ceiling. surplus electrons are added to each sphere, and then the spheres are brought in contact with each other and released. their equilibrium position is such that each string makes a 15.0 ∘ angle with the vertical.?
