A) \[8\,\,R\]
B) \[9\,\,R\]
C) \[10\,\,R\]
D) \[20\,\,R\]
Correct Answer: B
Solution :
Acceleration due to gravity at a height h from earth's surface \[g'=\frac{GM}{{{(R+h)}^{2}}}\] Since, \[g'=\frac{1}{100}\] of g \[\frac{g}{100}=\frac{GM}{{{(R+h)}^{2}}}\] \[\frac{{{(R+h)}^{2}}}{100}={{R}^{2}}\] \[\left[ \because \,\,\,g=\frac{GM}{{{R}^{2}}} \right]\] \[R+h=10R\] \[h=9R\]You need to login to perform this action.
