Question

What is the pressure gradient required to maintain a geostrophic wind at a speed of v = 10 m s?1 at 45? N? In the absence of a pressure gradient, show that air parcels flow around circles in an anticyclonic sense of radius v/f.

I think that this is the answer to the first part

?p/?x = ?fv

= 1 kg m?3 × 2 × 7.27 × 10?5 s?1 × sin (45?) × 10 m s^?1 = 1. 028 1 × 10?3 kg/(m^2s^2)

but I don't know what equation is being used for f.

I also don't know the answer to the second part of the question.
