A) \[\frac{1}{r}\]
B) \[\frac{1}{{{r}^{2}}}\]
C) \[{{r}^{2}}\]
D) \[r\]
Correct Answer: D
Solution :
Idea Here, earth is considered as a solid sphere of mass in mass Mg. The intensity of gravitational field is equal to\[\frac{G{{M}_{e}}}{R_{r}^{3}}r\] \[{{g}_{\text{inside}}}=\frac{G{{M}_{e}}r}{R_{e}^{3}}\Rightarrow {{g}_{\text{inside}}}\propto r\]You need to login to perform this action.
