Q11.Take a few pencils which are cylindrical in shape. Place them parallel to each other on a table. Place a thick book over it. Now push the book. You have to apply a minimum force of 2 N to generate motion. You observe the pencils rolling as the book moves. Now place the book on the table surface directly without placing the pencils. Push the book again. In this new condition you require a minimum force of 2.5 N to generate motion.
(i) Justify the difference between the magnitude of force in these two cases.(ii) Suggest a method by which you may reduce the force less than 2 N to push the same book to generate motion on the table surface as stated in the above example
