Question 1 IGCSE_MODEL_QUESTIONS_VOL1 • 2025 • PHYSICS • practical

A student measures the length of a metal rod using a metre rule that has a zero error of +2 mm (the rule reads 2 mm too long). Three successive readings are recorded: 0.452 m, 0.453 m and 0.451 m. The student takes the average of the three readings as the measured length. A calibrated steel gauge later shows that the true length of the rod is 0.447 m.

Question Parts

( a )

Calculate the average of the three recorded readings.

( b )

Correct the average length for the zero error of the metre rule.

( c )

Determine the percentage error of the corrected length with respect to the true length of 0.447 m.

( d )

Suggest two practical ways to reduce the measurement error in future experiments.
