This is general physics and its from Coulomb law. Answer this question STEP by STEP on a document or paper. 1) Two equal and equally charged spheres, 0.1 g of mass each, are suspended from the same point by threads of 13 cm in length. Due to the repulsion between the two, the spheres separate 10 cm as seen in the graphic representation. Find the charge of each of them. 13 cm A. m q 10 cm m q
