Question

what is the effect of rotation of earth on a boy on a x height from earths surface

Answer 1

$$\begin{gathered} \text{The body will experience a centrifugual force equl to}m{\omega }^{2}r. \\ \text{Where m is the mass of the body.}r\text{is the radius}=R+x,\text{where}R\text{is the radius} \\ \text{of the earth. And}\omega \text{is the angular velocity. So the acceleration due to} \\ \text{gravity will be} \\ g\text{'}=\frac{mg-m{\omega }^{2}r}{m}=g-{\omega }^{2}r \end{gathered}$$
