Question

What should be the angular velocity of rotation of the earth for objects lying a
equator to just fly off?​

Answer 1

Answer:

We can calculate how fast the Earth would need to spin to balance the force of gravity (this is known as the 'escape velocity'). It works out at about 28,437km/h (17,670mph). The Earth would have to spin once every 84 minutes to achieve that speed at the equator, or about 17 times faster than it actuallyspins.

Explanation:

The Earth rotates at a moderate angular velocity of 7.2921159 × 10−5 radians/second.
