A satellite is revolving round the earth in circular orbit

A

if mass of earth is made four times, keeping other factors constant, orbital speed of satellite will become two times

B

corresponding to change in part(a), times period of satellite will become half

C

when value of `G` is made two times orbital speed increases and time period decreases

D

`G` has no effect on orbital speed and time period

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`nu = sqrt((Gm)/(r ))`
or `nu prop sqrt(GM)`
`T = (2 pi)/(sqrt(GM))r^(3//2)`
or `T prop (1)/(sqrt(GM))`
