MCQ
If a satellite orbits as close to the earth's surface as possible,
- Aits speed is maximum
- Btime period of its rotation is minimum
- Cthe total energy of the 'earth plus satellite' system is minimum
- ✓all of the above
✓
Answer
Correct option: D.
all of the above
d
Speed of satellite $\alpha \frac{1}{\sqrt{r}}$ Speed will be maximum Time period
Speed of satellite $\alpha \frac{1}{\sqrt{r}}$ Speed will be maximum Time period
$\alpha r^{\frac{3}{2}}$ it will be minimum
Total Energy $=-\frac{G M m}{2 r}$
Total energy is minimum.
