Given below are two statements: Statement I: The centre of gravity of a small, homogeneous body coincides with its centre of mass. Statement II: The centre of gravity of an irregular flat cardboard can be determined experimentally by suspending it freely from two or more points and finding the intersection of the plumb lines. In the light of the above statements, choose the most appropriate answer from the options given below:

  1. Both Statement I and Statement II are correct.
  2. Both Statement I and Statement II are incorrect.
  3. Statement I is correct but Statement II is incorrect.
  4. Statement I is incorrect but Statement II is correct.

Correct answer · Option 1

Both Statement I and Statement II are correct.
