Question

Spherical capacitance, $$C$$, is defined as the ratio of the product of 4, $$\pi$$, vacuum permittivity, $$\epsilon_0$$, and Coulomb’s constant, $$k$$ to the difference between the ratio of 1 to the radial length $$a$$, and the ratio of 1 to the radial length $$b$$. Which of the following correctly solves spherical capacitance for radial length $$b$$?

Accepted Answer

$$b = \frac{Ca}{C - 4\pi k \epsilon_0 a}$$

Answer

$$b = \frac{C - 4\pi k \epsilon_0 a}{Ca}$$

Answer

$$b = \frac{Ca}{C + 4\pi k \epsilon_0 a}$$

Answer

$$b = \frac{Ca}{Ca - 4\pi k \epsilon_0 a}$$
