Assertion:- Elastic restoring forces may be conservative
Reason:- The value of strain for same stress are different while increasing the load and while decreasing the load.
Reason:- The value of strain for same stress are different while increasing the load and while decreasing the load.
View answer and explanation
Correct option: B
If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion
Option B (If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion) is correct because elastic restoring forces can be conservative, and hysteresis explains the difference in strain for the same stress during loading and unloading, but hysteresis doesn't explain why restoring forces *may* be conservative.
