                   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.
                       1.    Assertion: During charging by rubbing both body acquires opposite charge.             1
                            Reason: one body gains electron and one body looses electrons.
                       2.    Assertion: In charging by conduction both the bodies acquire similar charges.         1
                            Reason: The two bodies are not in contact during charging by conduction.
                   Fill in the blanks
                       3.    Charging by rubbing is also called charging by _________.                             1
                       4.    Both objects acquires _________ electrical charge in charging by conduction.          1
                       5.    _________ is a naturally occurring static electricity.                                1
