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 length and the diameter of the material being tested. A metre rule is ideal for measuring length accurately, while a micrometer provides precision in measuring the diameter of a wire or similar material. Together, these instruments allow for the accurate calculation of stress and strain needed to find the Young modulus.
