Two identical conducting spheres A and B, carry equal charge. They are separated by a distance much larger than their diameters, and the force between them is F. A third identical conducting spheres, C,is uncharged. Sphere C is first touched to A, then to B, and then removed. As a result, the force between A and B would be equal to :
Two small conducting spheres have charges 2.1 nC and -0.1 nC are touched to each other and then separated by a distance of 0.5 m. Find the force between them
Two identical conducting spheres 1 and 2 carry equal amounts of charge and are ficed apart at a certain distance larger than their diameters. The spheres repel each other with an electrical force of 88mN. A thired identical sphere 3, having an insulating handle and initially uncharged, is touched first to sphere 1 and then to sphere 2 and finally removed. Find the force between spheres 1 and 2 as shown if Figure. ,
Two conducting spheres of radii R each are given equal charges +Q and are kept such that their centre are at distance r (geR) . The force of attraction (F) between them is:
A conducting sphere of radius R and carrying a charge Q is joined to an uncharged conducting sphere of radius 2R . The charge flowing between them will be
Two identical spheres each of mass M and radius R are separated by a distance 3R. The force of attraction between them is proportional to
Two identical conducting spheres are charged by induction and then sepatatd by a large distance, sphere-1 has charge +Q and spher-2 has charge -Q. A third sphere is initially uncharged. If sphere-3 is touched to sphere-1 and sepatated and then touched to sphere-2 and separated what is the final charge on each of the three spheres?
There are two charged identical metal spheres A and B repel each other with a force 3xx10^(-5)N . Another identical uncharged sphere C is touched with A and then placed at the mid-point between A and B. Net force on C is
