Find the orbital velocity of an artifical satellite of the earth in an orbital close to the earth?

A

`8 "kms"^(-1)`

B

`11.2 "kms"^(-1)`

C

`3 xx 10^(8) "ms"^(-1)`

D

`2.2 xx 10^(3) "kms"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
Since, orbital velocity of body close to earth can be given as
`v_(o)=sqrt(rg)=sqrt(6400xx10^(3)xx10)=sqrt(64xx10^(6))=8xx10^(3) " ms"^(-1)`
`v_(o)=8 " kms"^(-1)`.
