QJEEM18Phf6bc: JEE Main 2018 Physics - Class 11 JEEM18Phf6bc Solution: Suppose that the angular velocity of rotation of earth is…
Suppose that the angular velocity of rotation of earth is increased. Then, as a consequence :
Multiple Choice Options
- A Weight of the object, everywhere on the earth, will increase.
- B Weight of the object, everywhere on the earth, will decrease.
- C There will be no change in weight anywhere on the earth.
- D Except at poles, weight of the object on the earth will decrease.
Step-by-Step Verified Solution
With rotation of earth the effect on acceleration due to gravity vary as
g' = g 2 R cos2
Here is lattitude.
At poles = 90o so those will be no change in gravity.
At all other point will increase so g' will decrease.
g' = g 2 R cos2
Here is lattitude.
At poles = 90o so those will be no change in gravity.
At all other point will increase so g' will decrease.
