The speed of earth's rotation about its axis is `omega`. Its speed is increased to `x` times to make the effective accel acceleration due to gravity equal to zero at the equator, then `x is around `(g= 10 ms^(-2) R = 6400 km)`

If the speed of rotation of earth about its axis is increased,

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 rotates about its own axis, then the value of acceleration due to gravity is

How is acceleration due to gravity affected by rotation of earth about its axis ?

Find the magnitude of the acceleration due to gravity at the surface of the earth. ( M = 6 xx 10^(24) Kg, R = 6400 Km)
