Statement I: Identical springs of steel and copper are equally stretched. More work will be done on the steel spring.
Statement II: Steel is more elastic than copper.

View answer and explanation

Correct option: A

Statement I is true and statement II is true

Option A is correct because Statement I is true as steel requires more work due to its higher Young's modulus, and Statement II is true because steel is indeed more elastic than copper.
