Answer:
The capacitance of a sphere of radius 10 cm situated in the air is approximately 11 × 10⁻¹²F.
Explanation:
The capacitance of a sphere is given by 4πϵ₀r, where r is the radius of the sphere.
As a result, the capacitance = 10⁻⁹/9 × 10/100 = 11 × 10⁻¹²F.
If the surrounding medium is the same, the capacitance of any sphere (C =4πε₀R), whether hollow or solid, will be the same. If the surrounding medium is air, capacitance C = 4πε₀R, where R is the sphere's radius.
Thus, for spherical conductors, the capacitance can be calculated by calculating the voltage differential between the conductors for a given charge on each.
