NEET Physics Orbital Motion Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Orbital velocity of a satellite | (i) 27.3 days |
| (b) Escape velocity from Earth | (ii) 1.52 times that of Earth |
| (c) Time period of the Moon | (iii) √(GM/R) |
| (d) Radius of Mars' orbit | (iv) 11.2 km/s |
a-iii, b-iv, c-i, d-ii
a-ii, b-iv, c-i, d-iii
a-iv, b-ii, c-iii, d-i
a-i, b-iii, c-ii, d-iv
Correct Answer
Detailed Explanation
The orbital velocity of a satellite can be calculated using the formula √(GM/R), while the escape velocity from Earth is approximately 11.2 km/s. The time period of the Moon is 27.3 days, and Mars' orbital radius is indeed 1.52 times that of Earth's orbital radius.
