Physics Question on Gravitation
At sea level, the value of g is minimum at
A
the poles
B
the equator
C
45∘ south latitude
D
45∘ north longitude
Answer
the equator
Explanation
Solution
Due to the rotation of the earth, the acceleration due to gravity for earth changes and at the equator, its value is given by g′=g−w2R And at poles g′=g ∴ The value of acceleration due to gravity is minimum at the equator.
