For a spherically symmetric earth, the acceleration due to gravity should be about the same at the equator and at the poles.

Question

Consider the following statements : 

(1) For a spherically symmetric earth, the acceleration due to gravity should be about the same at the equator and at the poles. 

(2) If earth suddenly stops rotating about its axis, then the value of g will be same at all the places. 

Which of these statement(s) is/are correct ? 

(a) (1) only 

(b) (2) only 

(c) Both (1) and 

(2) (d) Neither (1) nor (2)

Answer 1

The correct option is: (b) (2) only

Explanation:

There is a difference in acceleration due to gravity at equator and poles. The gravity is more on the poles due 2 factors:- 

(1) the effect due to the angular rotation of earth is minimum or zero at poles. 

(2) the earth is flat is towards the poles sog is more at poles.
