The angular speed of earth around its won axis is

The angular speed of earth around its own axis is

A train of mass m moves with a velocity upsilon on the equator from east to west. If omega is the angular speed of earth about its axis and R is the radius of the earth then the normal reaction acting on the train is

Which is greater : the angular velocity of hour hand of a watch or angular velocity of earth around its own axis ? Give their ratio.

Which is greater , the angular velicty of the hour hand of a watch or angular velocity of earth around its own axis ?

Is the angular speed of rotation of hour hand of a watch greater or smaller than the angular speed of earth's rotation about its axis ?

The angular speed of earth's rotation about its own axis is omega . When its angular speed is increased to n time its original angular speed, the acceleration due to gravity at the equator becomes zero. What is the value of n? [R is the equatorial radius of the earth]

The Earth takes slightly less than one day to complete one rotation about the axis passing through its poles. The actual time is 8.616xx10^(4) s. With this given information, what is the angular speed of the Earth about its axis?

The angular speed of rotation of earth about its axis at which the weight of man standing on the equator becomes half of his weight at the poles is given by

How will the value of g be effected if (i) the rotatio of the Earth about its polar axis stops and (ii) the rotational speed of the Earth about its polar axis is doubled?
