Three conducting spheres -1, 2, and 3-are shown below. Spheres 1 and 2 are initially neutral and Sphere 3 initially has a net positive charge. Spheres 2 and 3 are the same size, but Sphere 1 is larger, as indicated in the diagram. Note also that the center of Sphere 1 is about 10 times farther from the center of Sphere 3 as the radius of Sphere 3 2 3 A B C D Rank the charge density at each labeled point A-E, greatest first.

Solution
Charges will get induced on the sphere 1 and 2.
Now, the sphere which is closer, will have more induced charge effect.
Also, nearby negative charge will get induced. Therefore, on charge density basis, rank is
E > C > A > B > D = 0
