Question

What are the positions on the earth where the value ‘g’ is (i) maximum, (ii) minimum? Justify your answer.

Answer 1

• On earth value of g is maximum at poles and minimum at the equator.
• At poles radius of earth is slightly less, so value of g is more while at equator the radius of earth is slightly more, so the value of g is less, g = \(\frac { 1 }{ R }\)
