A) 50m
B) 25m
C) 12.5m
D) 19.6m
Correct Answer: C
Solution :
[b] For the satellite, the gravitational force provides the necessary centripetal force \[\frac{GMm}{{{(R+x)}^{2}}}=\frac{mv_{2}^{2}}{(R+x)}and\,\frac{GM}{{{R}^{2}}}=g\] \[{{v}_{0}}=\sqrt{\frac{g{{R}^{2}}}{R+x}}\]You need to login to perform this action.
