Which of the following is incorrect about acceleration due to gravity…

Variation in acceleration due to gravity (g)

1. Value of g decreases with height or depth from earth's surface.

2. g is maximum at poles.

3. g is minimum at equator.

4. g decreases due to rotation of earth.

5. g decreases if angular speed of earth increases and increases if angular speed of earth decreases.

• If angular speed of earth becomes 17 times its percent value, a body on the equator becomes weightless.
