12. What is the charge density o (in C/m²) on the outer surface of the outer shell?

(12-15) Consider two concentric conducting spherical shells. Inner shell carries an excess
charge of +2 µC and outer shell carries +2 µC. In the figure, the inner shell has an inner
radius of 0.1 m and an outer radius of 0.2 m, and the outer shell has an inner radius of 0.38 m
and an outer radius of 0.5 m.

Expert Solution

Step 1

Given:

The charge on the inner shell is $q = + 2 μC$ .

The charge on the outer shell is $q = + 2 μC$ .

The inner and outer radius of the inner shell is $r_{1} = 0.1 m and r_{2} = 0.2 m$ .

The inner and outer radius of the outer shell is $R_{1} = 0.38 m and R_{2} = 0.5 m$ .

Three identical metallic conducting spheres carry the following charges: q1 = +4.60 μC, q2 = +1.80 μC, and q3 = −1.60 μC. The spheres that carry the charges q1 and q2 are brought into contact. Then they are separated. After that, one of those two spheres is brought into contact with the third sphere that carries the charge q3; those two are then separated as well. How many excess (or deficiency) electrons make up the final charge on the third sphere?
