हिन्दीGiven 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:
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.
