A) \[\frac{5}{6}\frac{GM}{{{x}^{2}}}\]
B) \[\frac{8}{9}\frac{GM}{{{x}^{2}}}\]
C) \[\frac{7}{8}\frac{GM}{{{x}^{2}}}\]
D) \[\frac{6}{7}\frac{GM}{{{x}^{2}}}\]
Correct Answer: C
Solution :
| [c] Mass of the small part |
 |
 |
 |
 |
| g (rest part) = g (complete sphere) g (small part) |
 |
From far point  , so neglect  |
