Question

A measurement is recorded as 8.8 cm with an absolute uncertainty of 0.1 cm. This means the true value lies within which range?
Options
A 8.7 cm to 8.9 cm
Correct Answer
B 8.79 cm to 8.81 cm
C 0.1 cm to 8.8 cm
D 8.0 cm to 9.6 cm
Correct Answer

Option A is the correct answer.

Detailed Explanation

The absolute uncertainty, denoted by ±, indicates the interval in which the true value is expected to lie. For a measurement of (8.8 ± 0.1) cm, the true value is between 8.8 - 0.1 = 8.7 cm and 8.8 + 0.1 = 8.9 cm.

Hint

The '±' value is added to and subtracted from the measured value to define the range of possible values.
