NEET Physics Gravitational Potential Energy Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Escape Speed | (i) 11.2 km/s |
| (b) Total Mechanical Energy | (ii) Positive Value |
| (c) Gravitational Potential Energy at Infinity | (iii) Negative Value |
| (d) Binding Energy | (iv) Zero Value |
a-i, b-iii, c-iv, d-ii
a-i, b-ii, c-iv, d-iii
a-ii, b-iii, c-i, d-iv
a-i, b-iii, c-ii, d-iv
Correct Answer
Detailed Explanation
The escape speed from the earth's surface is given as 11.2 km/s. The total mechanical energy for a bound system is negative, while gravitational potential energy at infinity is zero. Binding energy is not a positive value but relates to the negative potential energy in a bound system.
