A) 8R
B) 9R
C) 10R
D) 20R
Correct Answer: B
Solution :
The acceleration due to gravity varies with height as \[g=\frac{g}{{{\left( 1+\frac{h}{R} \right)}^{2}}}\] \[\Rightarrow \] \[\frac{g}{100}=\frac{g}{{{\left( 1+\frac{h}{R} \right)}^{2}}}\] \[\Rightarrow \] \[{{\left( 1+\frac{h}{R} \right)}^{2}}=100\] \[\Rightarrow \] \[h=9R\]You need to login to perform this action.
