Calculation of Center of Mass: Practice Problem & Solution
Given below are two statements: Statement I: Centre of mass of any object always coincide with centre of gravity. Statement II: Centre of gravity is the point where total gravitational torque on the body is zero. In the light of the above statements, choose the most appropriate answer from the options given below.
Solution Explained:
To solve this problem, we apply the core principles of Calculation of Center of Mass. Understanding the underlying formula is key to arriving at the correct answer below:
Statement I is false because the center of mass and center of gravity only coincide in a uniform gravitational field. Statement II is true because the center of gravity is defined as the point about which the net gravitational torque is zero.
