GENERAL KNOWLEDGE

Detailed explanation-1: -If the earth suddenly stops rotating about its axis, there is no effect of centrifugal force on the gravitational acceleration. So, the value of gravitational will be same at all places.

Detailed explanation-2: -Assertion :If the earth suddenly stops rotating about its axis, then the acceleration due to gravity will become the same at all the places. Reason: The value of acceleration due to gravity is independent of rotation of the earth.

Detailed explanation-3: -If the Earth stopped spinning, you wouldn’t suddenly be launched off into space. Gravity would still keep you firmly on the ground. There would be lots of changes, though. If Earth were to stop spinning but continue to orbit the sun, a “day” would last half a year, and so would the night.

Detailed explanation-4: -At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.

Detailed explanation-5: -At latitudes nearer the Equator, the outward centrifugal force produced by Earth’s rotation is larger than at polar latitudes. This counteracts the Earth’s gravity to a small degree – up to a maximum of 0.3% at the Equator – and reduces the apparent downward acceleration of falling objects.
