Solution

Let g' be the acceleration due to gravity on Mount Everest.

\[\text { Then } g' = g\left( 1 - \frac{2h}{R} \right)\]

\[\text { here } h = 8848 m\]

\[ = 9 . 8\left( 1 - 0 . 00276 \right)\]

\[ = 9 . 0\left( 0 . 99724 \right)\]

\[ = 9 . 77  \ m/ s^2\]

∴ The acceleration due to gravity on the top of Mount Everest is 9.77 m/s2.
