Question

Statement 1: In order to make a body rotate, the net external force applied can be zero.

Statement 2: A body can even rotate in absence of any external force.

• A. Both statements are correct
• B. Both statements are incorrect
• C. Statement 1 is correct but statement 2 is incorrect
• D. Statement 1 is incorrect but statement 2 is correct

Answer 1

The correct option is C

Statement 1 is correct but statement 2 is incorrect

Even if ${\overrightarrow{F}}_{net}=0$ they can form a couple and thus can produce the rotational effect upon the body.

But if there is no force at all then nothing can produce the rotational effect.
