Acceleration Due to Gravity and its variation: Practice Problem & Solution
The dependence of acceleration due to gravity 'g' on the distance 'r' from the centre of the earth, assumed to be a sphere of radius R of uniform density, is as shown in figure below:-The correct figure is :
Solution Explained:
To solve this problem, we apply the core principles of Acceleration Due to Gravity and its variation. Understanding the underlying formula is key to arriving at the correct answer below:
\[ g= \frac{GMr}{R^{3}} \] for internal point
\[ g= \frac{GM}{r^{2}} \] for external point
