Which one of the following statements about the coriolis force is not correct?

The Coriolis effect is the result of

A small body is placed on the top of a smooth sphere of radius $R$ initially at rest. Then the sphere is imparted a constant acceleration $a=\frac{g}{2}$ in the horizontal direction and the body begins sliding down. If the angle is ${\theta }_0$ between the vertical and the radius vector drawn from the centre of the sphere to the break-off point, calculate $\cos {\theta }_0$ (Best approximation)
