NEETPhysicsElectrostatics
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Electrostatic potential is a relative physical quantity. Reason (R) : Electric potential difference is an absolute physical quantity. 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
B. Both (A) and (R) are true and (R) is NOT the correct explanation of (A).
Step-by-step solution
Assertion (A): Electrostatic potential is a relative physical quantity. - This is true because the electrostatic potential at a point is defined relative to some reference point (often taken at infinity). Hence, it is a relative quantity. Reason (R): Electric potential difference is an absolute physical quantity. - This is false. Electric potential difference is also a relative quantity because it is the difference in potential between two points. It depends on the choice of the reference points, so it is not absol
