Physics · SYSTEMS OF PARTICLES AND ROTATIONAL MOTION

Given below are two statements: Statement I: For the mechanical equilibrium of a rigid body under coplanar forces, exactly three independent scalar conditions must be satisfied. Statement II: If a rigid body is in rotational equilibrium about one reference origin, it must necessarily be in rotational equilibrium about every other origin, irrespective of whether the net external force on the body is zero or non-zero. In the light of the above statements, choose the most appropriate answer from the options given below:

1. A
   Both Statement I and Statement II are correct.
2. B
   Both Statement I and Statement II are incorrect.
3. C
   Statement I is correct but Statement II is incorrect.
4. D
   Statement I is incorrect but Statement II is correct.
