Question
On the surface of the earth, the weight of a body is:
- More at equators
- b
- Same at poles and equators
- It remains zero at poles
Hint:
The gravitational force is directly proportional to the radius of the earth.
The correct answer is: b
The correct option is b)More at poles.
Because the poles are less from the center of the earth than the equator, the gravitational pull on the body is greater at the poles than at the equator. Therefore, body weight is greater at the poles.
