Given below are two statements: Statement I: The centre of gravity of a body coincides with its centre of mass in uniform gravity or gravity-free space. Statement II: If a body is extended such that gravity varies from part to part, the centre of gravity and centre of mass will still coincide. 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.
View Answer & Solution

Correct answer · Option C

Statement I is correct but Statement II is incorrect.

Explanation

Statement I is correct because uniform gravity ensures CG and CM coincide. Statement II is incorrect because if \( g \) varies, CG and CM do not coincide.
