Physics · UNITS AND MEASUREMENT
हिन्दीConsider the measured values: (i) \( 0.002308\text{ m} \), (ii) \( 2.3080\text{ m} \), (iii) \( 23080\text{ m} \), and (iv) \( 2.308 \times 10^3\text{ m} \). The number of significant figures in these measurements are respectively:
Correct answer · Option 1
4, 5, 4, 4
Explanation
(i) Leading zeros are non-significant (4 S.F.). (ii) Trailing zero after decimal is significant (5 S.F.). (iii) Trailing zero without decimal is non-significant (4 S.F.). (iv) Power of 10 is irrelevant, base number has 4 S.F. Thus 4, 5, 4, 4.
