Assertion :Out of three measurements l = 0.7 m; l = 0.70 m and l = 0.700 m, the last one is most accurate.

Reason : In every measurement, only the last significant digit is not accurately known.

अभिकथन: तीन मापों, l = 0.7 m; l = 0.70 m और l = 0.700 m, में से अंतिम वाला सबसे यथार्थ है।

कारण: प्रत्येक माप में, केवल अंतिम सार्थक अंक यथार्थ रूप से ज्ञात नहीं है।

  1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
  2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
  3. If the assertion is true but the reason is false
