Acceleration due to GravityHardQuestion 6213
Question
g varies with latitude because Earth:
- AIs spherical
- BRotates (centrifugal effect) and is oblateCorrect
- CHas oceans
- DHas atmosphere
Correct answer
Rotates (centrifugal effect) and is oblate
Explanation
g is maximum at poles (minimum r, no centrifugal effect) and minimum at equator — due to rotation and oblate shape.
