The earth, radius 6400 km, makes one revolution about its own axis in 24 hours. The centripetal acceleration of a point on its equator is nearly

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

How many degrees does the Earth rotate about its own axis in one hour?

Radius of earth is 6400 km and that of mars is 3200 km. Mass of mars is 0.1 that of earth's mass. Then the acceleration due to gravity on mars is nearly

Radius of earth is 6400 km and that of mars is 3200 km. Mass of mars is 0.1 that of earth's mass. Then the acceleration due to gravity on mars is nearly

If the radius of the rarth is 6400 km, then the linear velocity of a point on the equator will be nearly

If the radius of the rarth is 6400 km, then the linear velocity of a point on the equator will be nearly

What should be the velocity of earth due to rotation about its own axis so that the weight at equator become 3/5 of initial value. Radius of earth on equator is 6400 km

What should be the velocity of earth due to rotation about its own axis so that the weight at equator becomes 2/5 of initial value? Radius of earth on equator is 6400 km and is 10 m/s^2 .
