If the Earth stops rotation on its axis, then what would be the change in the value of gravitational acceleration at equator and poles? |
|
Answer» The value of gravitational acceleration (in latitude), g’ = g – ω2Rcos2 λ (i) For poles, λ = 90°, ∴ cos2 λ = 0 Therefore g’ = g Therefore, even the Earth stops its rotation, i.e, ω = 0, there will be no change in gravitational acceleration. (ii) For equator, λ = 0. ∴ cos λ = 1 If ω = 0 i.e., Earth stops rotation, then g’ = g Thus the value of gravitational acceleration increase on the equator when Earth stops it’s rotation. |
