NEET Physics Significant Figures MCQ Question
Consider a diagram showing a series of measurements: 0.00452 m, 45.300 m, and 6000 m. Which statement correctly identifies the number of significant figures for each measurement?
0.00452 m has 3 significant figures, 45.300 m has 5 significant figures, and 6000 m has 1 significant figure.
0.00452 m has 4 significant figures, 45.300 m has 4 significant figures, and 6000 m has 3 significant figures.
0.00452 m has 3 significant figures, 45.300 m has 4 significant figures, and 6000 m has 4 significant figures.
0.00452 m has 2 significant figures, 45.300 m has 5 significant figures, and 6000 m has 2 significant figures.
Correct Answer
Detailed Explanation
0.00452 m has 3 significant figures as the leading zeros are not significant. 45.300 m has 5 significant figures because trailing zeros in a number with a decimal point are significant. 6000 m has 1 significant figure as trailing zeros in a whole number without a decimal point are not significant.
