Physics · GRAVITATION

At what height \( h \) above the surface of the Earth does the acceleration due to gravity become \( \frac{g}{9} \), where \( g \) is the value of acceleration due to gravity on the Earth's surface and \( R_E \) is the Earth's radius?

1. A
   \( h = 2R_E \)
2. B
   \( h = 3R_E \)
3. C
   \( h = 8R_E \)
4. D
   \( h = \frac{R_E}{2} \)
