NEETPhysicsCapacitance
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
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
C. (A) is true but (R) is false.
