Worked Solution & Example Answer:A student carries out an investigation to determine the Young modulus of a material - Edexcel - A-Level Physics - Question 2 - 2023 - Paper 2
Step 1
B metre rule and micrometer
Answer
To determine the Young modulus of a material, the student needs to measure both the dimensions of the material and the extension when a load is applied.
- Measuring Length: The metre rule is suitable for measuring the length of the material accurately.
- Measuring Diameter: The micrometer enables precise measurement of the cross-sectional area, which is essential for calculating stress.
Thus, option B provides the necessary instruments for this investigation.
