Question

A book is kept on a table. When the table is pushed, it accelerates forward. If the book moves along with the table, what can we say about friction acting on the book?

• A. No other frictional force
• B. It will feel a sliding frictional force
• C. it will feel a rolling frictional force
• D. Cannot be said

Answer 1

The correct option is A No other frictional force

Since the book is accelerating along with the table, friction will act in the direction of motion of the book. This is because friction is the only force that is acting in horizontal direction. Also, as there is no slipping between the table and the book, static friction will come into play.
