Using orbital radius r and the corresponding periodic time T of different satellite revolving around a planet, what would be the slope of graph of log T rarrlog r ?

Answer»

`3/2`
`2/3`
3
2

Solution :`implies` If the period of stallite revolves ROUND the planet in orbit of RADIUS R is T ,
`T = kr^(3/2 )` where `k = (4pi2)/(GM)`constant
`:. logT = logk +3/2` logr comparing this equation with y = c + nxslope `m = 3/2`
