Consider the following statements:

If the net external torque acting on an object is switched off, then

1. linear momentum will remain unchanged

2. angular momentum will remain unchanged

Which of the statements given above is/are correct?

View answer and explanation

Correct option: B

2 only

Option B (2 only) is correct because if the net external torque is zero, angular momentum is conserved, but linear momentum depends on net external force.
