Question
Answer the following: You are given a thread and a metre scale. How will you estimate the diameter of the thread?
✓

Answer

Wrap the thread on a uniform smooth rod in such a way that the coils thus formed are very close to each other. Measure the length of the thread using a meter scale. The diameter of the thread is given by the relation.
