A Geo-stationary satellite bits around the earth in a circular of radius 36, 000 km then what will be the time period of a spy satellite orbiting a few hundred km above the earth's surface `(R_("earth") = 6400 km)`

A

(a) `1/2`

B

(b) 1

C

(c) 2

D

(d) 4

Text Solution

Verified by Experts

The correct Answer is:
C
`(T_(2))/(T_(1)) =((a_(2))/(a_(1)))^(3/2) rArrT_(2)=24((6400)/(3600))^(3/2) = 2 ` hours
