MHT CET 2024 Physics question
The speed with which the earth would have to rotate about its axis so that a person on the equator would weigh th as much as at present weight is (g = gravitational acceleration, R= equatorial radius of the earth)
Answer: (A)
Solution
At the equator the apparent weight is (the centrifugal term opposes gravity). We need , so . Hence and $ω =
