A) will be same at all points of the orbit
B) will be maximum when it is at maximum distance from earth
C) will be maximum when its distance from the earth will be minimum
D) goes on increasing or decreasing continuous in dependines upon the mass of the satellite
Correct Answer: C
Solution :
According to Kepler's law \[{{T}^{2}}\propto {{r}^{3}}\] \[\omega =\frac{2\pi }{T}\]or\[T=\frac{2\pi }{\omega }\] \[\frac{4{{\pi }^{2}}}{{{\omega }^{2}}}\propto {{T}^{3}}\]or\[{{\omega }^{2}}\propto \frac{1}{{{r}^{3}}}\] So, speed\[\omega \]will be maximum when distance from the earth r is minimum.You need to login to perform this action.
