Question
Consider two identical conducting spheres, each hanging at the end of an insulating thread. If such a pair of spheres are allowed to touch briefly (and in a region far from the influence of other charges), it is found that afterward they carry equal electric charge. This is as one should expect on the basis of symmetry.Use this experimental result, and any other physical principles that are appropriate, to answer the questions that follow.Given below are several cases with different initial net charge carried by each of the two spheres. Predict in each case the final net charge carried by any one of the spheres after they touch together briefly.Before touching: Sphere A = 18.5 nC Sphere B = 0 nC What is the charge of any of the two spheres after touching, in nC?Explanation / Answer
they will split the charge evenly so q final = (18.5+0)/2 = 9.25 nC
