Question 196 of 223

The time period of an earth satellite in circular orbit is independent of

Show answer and solution

Answer: (A) the mass of the satellite

The time period of satellite is given by
T=2π(R+h)3GMT=2 \pi \sqrt{\frac{(\mathrm{R}+\mathrm{h})^3}{\mathrm{GM}}}
where, R+h=\mathrm{R}+\mathrm{h}= radius of orbit satellite, M=\mathrm{M}= mass of earth.
