1.	In the following question, statement 1 refers assertion and statement 2 refers reason. Statement 1: During perfect rolling, thefrictional force is zero. Statement 2: The velocity at the point of contact becomes zero. Select the correct option.
Answer» Statement 1 and 2 are true and statement 2 is a CORRECT explanation for statement 1. Statements 1 and 2 are true and statement 2 is not a correct explanation for statement 1. Statement 1 is true and statement 2 is false. Statement 1 is false and statement 2 is true. Solution :The frictional force DECREASE the velocity of the body at the point of CONTACT. When velocity becomes ZERO and force of friction becomes zero. So, no work is done.
