Two spherical shells have a common center. The inner shell has a radius of 5.00 cm and a charge of [tex]+4.00 \times 10^{-6} \text{ C}[/tex]. The outer shell has a radius of 15.0 cm and a charge of [tex]-5.00 \times 10^{-6} \text{ C}[/tex].

What is the charge of the inner shell?

A) [tex]+4.00 \times 10^{-6} \text{ C}[/tex]
B) [tex]-4.00 \times 10^{-6} \text{ C}[/tex]
C) [tex]+5.00 \times 10^{-6} \text{ C}[/tex]
D) [tex]-5.00 \times 10^{-6} \text{ C}[/tex]

Answer :

Final answer:

The charge of the inner shell, as specified in the question, is +4.00×10(-6)C, which remains an intrinsic characteristic unless an external action alters it.

Explanation:

The question presents a scenario with two spherical shells having a common center, where the inner shell has a charge of +4.00×10(-6)C, and the outer shell has a charge of -5.00×10(-6)C. The question asks for the charge of the inner shell. Based on the information provided, the charge of the inner shell is already specified in the question. Therefore, the answer is A) +4.00×10(-6)C. This demonstrates the basic principles of electrostatics, emphasizing that the charge of an object is an intrinsic property that doesn't change unless an external action is performed (such as transferring charge).
