Two isolated conducting spheres are separated by a large
distance. Sphere 1 has a radius of 20 cm and an initial charge 30
nC while Sphere 2 has a radius of 60 cm and an initial charge 70
nC. A very thin copper wire is now connected to the spheres to
allow charge to ﬂow between them. How much charge will be
transferred from Sphere 2 to Sphere 1? (Note that the charge
transferred can be positive, negative or zero.)
Dear student,
Find this solution, and RATE IT ,If you find it is helpful .your rating is very important to me.If any incorrectness ,kindly let me know I will rectify them soon.
Thanks for asking ..

Two spherical conductors are separated by a distance much larger than either of their radii. Sphere A has a radius of 46.5 cm and a net charge of -95.5 nC, whereas sphere B, which is initially neutral, has a radius of 94.4 cm. The two spheres are then connected by a thin metal wire. What is the charge on sphere B after equilibrium has been reached? charge on sphere B: -31.52 nc
Charge is placed on two conducting spheres that are very far apart and connected by a long thin wire. The radius of the smaller sphere is 5 cm and that of the largersphere is 12 cm. The electric field at the surface of the larger sphere is 630 kV/m. Find the surface charge density on each sphere.

Identical isolated conducting spheres 1 and 2 have equal charges and are separated by a distance that is large compared with their diameters. The electrostatic force acting on sphere 2 due to sphere 1 is F. Suppose now that a third identical sphere 3, having an insulating handle and initially neutral, is touched first to sphere 1, then to sphere 2, and finally removed. The electrostatic force that now acts on sphere 2 has magnitude F'. What is the ratio...
