हिन्दीConsider the following measured values: (i) \( 0.002030\text{ m} \), (ii) \( 2.030 \times 10^3\text{ m} \), (iii) \( 2030\text{ m} \). The number of significant figures in (i), (ii), and (iii) respectively are:
Correct answer · Option 1
\( 4, 4, 3 \)
Explanation
Leading zeros are not significant, trailing zeros after a decimal are significant, and trailing zeros without a decimal are not significant. Hence (i) has 4, (ii) has 4, and (iii) has 3 significant figures.
