Metal sphere A of radius 12.0 cm carries 6.00 μC of charge, and metal sphere B of radius 18.0 cm carries −4.00 μC of charge. If the two spheres are attached by a very long conducting thread, what is the final distribution of charge on the two spheres?
Given info: Sphere A has radius
Explanation:
The net charge is,
Substitute
Both the spheres will have the same potential. Therefore,
On Re-arranging,
Substitute the above equation the expression for the net charge and re-arrange
