If the angular velocity of a rotating rigid body is increased then its moment of inertia about that axis
If omega is the angular velocity of rotation of the earth about its axis and R is radius of the earth, to decrease the weight of a body near the equator by 40% , then the new angular speed should be
If the speed of rotation of earth about its axis is increased,
The numerical value of the angular velocity of rotation of the earth should be…….. Rad/s in order to make the effective acceleration due to gravity equal to zero.
What should be the angular velocity of rotation of Earth about its own axis so that the weight of body at the equator reduces to 3/5 of its present value? (Take R as the radius of the Earth)
