Question

Two spherical conductors A and B of radii a and b
(b > a) are placed concentrically in air. The two are connected by a copper wire as shown in figure. Then the equivalent capacitance of the system is

• A. $4\pi\varepsilon_{0}\frac{ab}{b - a}$
• B. 4 (a + b)
• C. 4πε₀
• D. 4πε₀

Answer 1

Answer: (C)

4πε₀

Answer 2

It is single conductions sphere of radius b

Ž C = 4pĪ₀b
