               INSTRUCTIONS:
               Please solve or paste the worksheet in the Physics Copy.
               For Assertion& Reason question follow the following directions.
               DIRECTION: Each of these questions contains an Assertion followed by Reason. Read them
               carefully and answer the question on the basis of following options. You have to select the one that
               best describes the two statements.
               (a) If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
               (b) If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
               (c) If Assertion is correct but Reason is incorrect.
               (d) If Assertion is incorrect but Reason is correct
               (e) If Assertion & Reason both are incorrect.
