The number of significant figures in the measurement 0.0050200 m is: MCQ with Answer and Explanation

The number of significant figures in the measurement 0.0050200 m is:
A. 5
B. 7
C. 8
D. 3
Answer: Option A
Solution (By JKSSB Mock Tests)
According to the rules of significant figures, leading zeros (0.00) are never significant as they only indicate the position of the decimal point. However, trailing zeros after a decimal point are always significant. Therefore, in 0.0050200, the significant digits are 5, 0, 2, 0, and 0, making a total of 5 significant figures.
