A) \[8\,R\]
B) \[9\,R\]
C) \[10\,R\]
D) \[20\,R\]
Correct Answer: B
Solution :
The gravitational acceleration at a height from the earth's surface is given by \[{{g}_{n}}=\frac{g{{R}^{2}}}{{{(R+h)}^{2}}}\] Given, \[gh=\frac{g}{100}\] \[\frac{g\,{{R}^{2}}}{{{(R+h)}^{2}}}=\frac{g}{100}\] or \[R+h=10R\] or \[h=9R\]You need to login to perform this action.
