The speed of a point A due to the rotation of the earth is twice that of a point B.If A is on latitude 22°N.calculate the latitude of B

  • Maths -

    Check the diagram. The radius of the latitude at angle θ is r*cosθ.

    Since speed is proportional to the radius of rotation, if B is at angle θ,

    r cos22° = 2r cosθ
