Question
Which of the following statements are true about acceleration due to gravity ?
Options
A.′g′ decreases in moving away from the centre if r > R
B.′g′ decreases in moving away from the centre if r < R
C.′g′ is zero at the centre of earth
D.′g′
Solution
Variation of g with distance
variation of g with w : g′ g - ω2Rcos2λ
If ω = 0 then g will not change at poles where cosλ = 0.
variation of g with w : g′ g - ω2Rcos2λ
If ω = 0 then g will not change at poles where cosλ = 0.
