If two springs and of force constants and , respectively, are stretched by the same force, it is found that more work is done on spring than on spring .Statement 1: If stretched by the same amount, work done on , will be more than that on .Statement 2: .
- AStatement 1 is false, Statement 2 is true
- BStatement 1 is true, Statement 2 is false
- CStatement 1 is true, Statement 2 is the correct explanation for statement 1
- DStatement 1 is true, Statement 2 is true, Statement 2 is not the correct explanation for statement 1
Solution & Step-by-step Explanation
Work done on a spring when stretched by a force is .Given for the same force :
So, Statement 2 is true.Now, if they are stretched by the same amount , the work done is .Since , then will be less than .Therefore, Statement 1 is false.
So, Statement 2 is true.Now, if they are stretched by the same amount , the work done is .Since , then will be less than .Therefore, Statement 1 is false.
