Answer 2

Answer:

A)  1.1 × 10⁻¹⁰F

Explanation:

Capacitance is described as the ratio of the change in an electric charge in a system that corresponds to the change in its overall electric potential.

The capacity of an isolated spherical conductor is given as -

C = 4πeoR

Where r = radius of spherical conductor

Thus,

C = 4πeoR = 1/9×10⁹R

wherein it will be -

C = 1.1 × 10⁻¹⁰F

Thus, the capacitance (in F) of a spherical conductor with radius 1 m is 1.1 × 10⁻¹⁰
