Identical isolated conducting spheres 1 and 2 have equal charges q and are separated by a distance r large compared to the diameters of the spheres. The electrostatic force acting on sphere 2 due to sphere 1 is 10-6 N. Suppose now, that the third identical conducting sphere 3, having an isolating handle, and initially electrically neutral, is touched first to the sphere 1, then to the sphere 2, and finally removed. Find the electrostatic force which will be acting on the sphere 2 after these manipulations.
