हिन्दीHow many significant figures are present in each of the following numbers, respectively: \( 0.0052 \), \( 2.005 \), and \( 0.200 \)?
Correct answer · Option 3
\( 2, 4, 3 \)
Explanation
Leading zeros are not significant, so \( 0.0052 \) has 2; zeros between non-zero digits are significant, so \( 2.005 \) has 4; trailing zeros after a decimal point are significant, so \( 0.200 \) has 3.
