Question 406: Gravitation

Question

Starting from the centre of the earth having radius R, the variation of g (acceleration due to gravity) is shown by

Accepted Answer

Since, acceleration due to gravity is given as
$$g = \left\{ {\matrix{
   {{4 \over 3}\pi \rho Gr} & {r \le r}  \cr 
   {{4 \over 3}\pi \rho G{{{R^3}} \over {{r^2}}}} & {r > R}  \cr

} } \right.$$
