Question
Let g be the acceleration due to gravity at earth's surface and k be the rotational K.E of earth suppose the earth's radius decreases by 2% keeping alt other quantities same then
- g decreases by 2% and K decreases by 4%
- g decreases by 4% and k increases by 2%
- g increases by 4% and K increases by 4%
- g decreases by 4% and K increases by 4%
The correct answer is: g increases by 4% and K increases by 4%
