Q 1. For a freely falling body from the height ‘h’ on the surface of the earth in the northern hemisphere with a latitude ‘θ’, show that the deviation of the body towards the east at the final stage is given by 13wCosθ(8h3/g)1/2\frac 1 3 w Cosθ(8h^3/g)^{1/2}, where ω\omega is the angular velocity of the earth and ‘g’ is the acceleration due to gravity.
