AIIMS 2018 Physics Center of Mass MCQ Question

The center of mass of a half disk is located at a distance of $\frac{4a}{3\pi}$ from the flat edge, where $a$ is the radius of the half disk. This result can be derived using integration techniques that account for the uniform distribution of mass in the half disk. Since options A, C, and D are not provided with any relevant information or calculations, they cannot be considered correct in this context. Understanding the center of mass is crucial in physics, as it helps in analyzing the motion and stability of objects.
