If weight of an object at pole is 196 N then weight at equator is [`g = 10 m/s^2` , radius of earth = 6400 Km]

The weight of a person on pole is 48N then the weight on equator is? (R= 6400km)

What should be the angular speed of earth in radian/second so that a body of 5 kg weights zero at the equator? [Take g = 10 m//s^2 and radius of earth = 6400 km]

What should be the angular speed of earth in radian/second so that a body of 5 kg weights zero at the equator? [Take g = 10 m//s^2 and radius of earth = 6400 km]

Suppose the earth increases it speed of rotation. At what new time period will the weight of a body on the equator becomes zero ? (Take, g = 10 ms^(-2) and radius of earth R = 6400 km)

Suppose the earth increases it speed of rotation. At what new time period will the weight of a body on the equator becomes zero ? (Take, g = 10 ms^(-2) and radius of earth R = 6400 km)

What is the time period of rotation of the earth around its axis so that the objects at the equator becomes weightless ? ( g = 9.8 m//s^(2) , Radius of earth= 6400 km)
