Question

How many significant figures are there in the number 0.062 cm?
Options
A 1
B 2
Correct Answer
C 3
D 4
Correct Answer

Option B is the correct answer.

Detailed Explanation

Leading zeros (zeros to the left of the first non-zero digit) never count as significant figures. In 0.062, the leading zero and the zero immediately after the decimal are placeholders. The significant figures are '6' and '2', so there are 2 significant figures.

Hint

Apply the rule for leading zeros: they indicate the position of the decimal point and are not counted as significant.
