A) \[x={{h}^{2}}\]
B) \[x=0.5h\]
C) \[x=2h\]
D) \[x=h\]
Correct Answer: C
Solution :
\[g=g\left( 1-\frac{2h}{R} \right)\] \[\Rightarrow \] \[g=g\left( 1-\frac{x}{R} \right)\] \[g=g\] \[\Rightarrow \]\[g\left( 1-\frac{2h}{R} \right)=g\left( 1-\frac{x}{R} \right)\] \[x=2h\]You need to login to perform this action.
