प्रश्न
State two factors on which the position of center of gravity of a body depends.
Advertisements
उत्तर १
The centre of gravity of a body depends upon:
- Body’s weight
- Body’s shape
- Axis of symmetry
- Distribution of weight
उत्तर २
The position of the center of gravity of a body depends on:
- The distribution of mass in the body: The center of gravity is located where the mass is more concentrated. If the mass distribution changes (e.g., by bending an object), the position of the C.G. also changes.
- The shape or geometry of the body: The center of gravity is determined by the shape of the body. For symmetrical bodies with uniform density, the C.G. is at their geometric center.
Notes
Students should refer to the answer according to their questions.
