A) \[x=\frac{\pi }{2},\]
B) \[-\frac{1}{6}\]
C) \[-\frac{1}{24}\]
D) \[-\frac{1}{48}\]
Correct Answer: C
Solution :
Energy required to raise a satellite upto a height h,\[\mu ,\] ...(i) \[\frac{2}{a}\] energy required to put in orbit \[\frac{5}{12}\] \[\frac{1}{5}\] as \[\frac{2}{5}\]orbital speed \[\text{ }\!\!\theta\!\!\text{ }\] \[{{\mu }_{s}}.\]\[\tan \theta \ge 3{{\mu }_{s}}\] ?(ii) From Eqs. (i) and (ii), we get\[\tan \theta >3{{\mu }_{s}}\]You need to login to perform this action.
