A satellite is moving round the earth in a circular orbit. The following statements are given.
(`i`) It is moving with a constant velocity.
(`ii`) It suffers no acceleration.
(`iii`) its angular momentum w.r.t. the earth remains conserved.
(`iv`) Its distance from centre must be equal to `sqrt(2)` times of earth's radius.
The correct option is

A

`(i)` and `(ii)` are true

B

`(i)` , `(iii)` and `(iv)` are true

C

only `(iii)` is true

D

`(i)` and `(iv)` are true

To solve the question regarding the satellite moving around the Earth in a circular orbit, let's analyze each statement one by one. ### Step-by-Step Solution: 1. **Statement (i): It is moving with a constant velocity.** - A satellite in a circular orbit is constantly changing its direction of motion. While the speed (magnitude of velocity) remains constant, the direction of the velocity vector changes continuously. Therefore, the velocity is not constant. - **Conclusion**: This statement is **false**. ...
