Given a net charge of +2Q transferred to a spherical conducting shell of inner radius a and outer radius b, what is the charge density on the outside of the conducting shell?
Given a net charge of +2Q transferred to a spherical conducting shell of inner radius a and outer radius b, what is the charge density on the outside of the conducting shell?
- 2Q/a^2
- 0
- 2Q/(b^2 - a^2)
- 2Q/b^2 (correct)
If the point charge placed in the center of the conducting shell is changed to +9q instead of -9q, what will be the charge density on the outside of the conducting shell?
If the point charge placed in the center of the conducting shell is changed to +9q instead of -9q, what will be the charge density on the outside of the conducting shell?
- 0 (correct)
- 2Q/(b^2 - a^2)
- 2Q/a^2
- 2Q/b^2
If the inner radius of the conducting shell is reduced to zero (a = 0), what will be the charge density on the outside of the conducting shell?
