1. |
The total energy of the particle will be zero at a large distance. |
2. |
The gravitational potential energy of the particle at the centre will be \(\frac{3}{2}\) times that of at the surface of the planet. |
3. |
The gravitational potential energy of the particle at the centre of the plant will be zero. |
4. |
Both statements (1) and (2) are correct. |
