NEET Physics Gravitational Potential Energy Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Total Mechanical Energy | (i) Negative for bound systems |
| (b) Escape Speed | (ii) 11.2 km/s |
| (c) Change in Kinetic Energy | (iii) Reduces during orbital transfer |
| (d) Potential Energy in Orbit | (iv) Given by -mMG/r |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-iii, c-ii, d-i
a-iii, b-iv, c-i, d-ii
Correct Answer
Detailed Explanation
The total mechanical energy is defined as the sum of kinetic and potential energies, and it is negative for bound systems. The escape speed from the Earth's surface is 11.2 km/s, and the change in kinetic energy reduces during orbital transfer, aligning with the pairs in option A.
