Sphere

Consider three identical metal spheres A, B and C. Spheres A carres charge + 6q carries no charge . Spheres A and B are touchd together and them separated. Sphere C is then touched to sphere A and separated from it . Finally the sphere C is touched to sphere B and separated from it . Find the final chage on the sphere C .

Three metallic spheres A, B and C having radii are in ratio 1 : 2 : 3 . Charge on sphere A is 6 mu C and sphere B and C are electrically neutral. If sphere A first contact with sphere B and then from C and ultimately contact from sphere B, then now charge on spheres A, B and C respectively will be-

The diagram shows the arrangement of three small uniformally charged spheres, A,B and C . The arrow indicate the direction of the electrostatic forces acting between the spheres (for example, the left arrow on sphere A indicates the electronstatic force on sphere A due to sphere B ). At least two of the spheres are positively charged. Which sphere, if any, could be negatively charged?

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?

Consider a solid sphere placed in surrounding with small temperature difference between sphere's surface and surrounding. If DeltaT and r represent temperature difference (between sphere and surrounding) and radius of sphere respectively, rate of cooling of the sphere is directly proportional to:

When two spheres carrying same charge but a different radii are connected by a conducting wire, the charge flows from smaller sphere to large sphere. Smaller sphere is at high potential when equal charges are imparted to both the spheres.
