Identical isolated conducting spheres 1 and 2 have equal charges and are separated by a distance that is large compared with their diameters. the magnitude of the electrostatic force acting on sphere 2 due to sphere 1 is f = 0.42 n. suppose now that a third identical sphere 3, having an insulating handle and initially neutral, is touched first to sphere , then to sphere 2, and finally removed. what is the magnitude of the electrostatic force f' that now acts on sphere 2?
