Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : It is not possible to make a spherical conductor of capacitance one farad. Reason (R) : It is possible for earth as its radius is 6400 km. In the light of the above statements, choose the most appropriate answer from the options given below:

Options

  1. ABoth (A) and (R) are true and (R) is the correct explanation of (A).
  2. BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
  3. C(A) is true but (R) is false.
  4. D(A) is false but (R) is true.

Correct answer

C. (A) is true but (R) is false.

Step-by-step solution

(C=4 \pi \varepsilon_0 R \Rightarrow 1=19×109\frac{1}{9 \times 10^9}R \Rightarrow R=9 ×\times10^9  m\mathrm{~m})
