A) \[gx\]
B) \[\frac{gR}{R-x}\]
C) \[\frac{g{{R}^{2}}}{R+x}\]
D) \[{{\left( \frac{g{{R}^{2}}}{R+x} \right)}^{1/2}}\]
Correct Answer: D
Solution :
[d] The gravitational force exerted on satellite at a heightis |
where, mass of the earth. |
Since, gravitational force provides the necessary centripetal force, so |
(where,is orbital speed of satellite) |
