Question
Which of the following statement is correct?
I. Value of βgβ is higher at poles than equator
II. Weight of an object at moon is 1/6 the weight of the object at earth
Solution
The value of the acceleration due to gravity at the pole is larger than at the equator because the poles are closer to the center of the earth due to the earth's oblateness. The mass of moon is 1/100 times and its radius 1/4 times that of earth As a result , the gravitational attraction on the moon is about one sixth when compared to earth.
