Air is blowing across the horizontal wings of an aeroplane in such a way that its speeds below and above the wings are 80 m/s and 120 m/s respectively. If the density of air is 1.2 kg/m^3 then the pressure difference between the lower and the upper sides of the wings will be

A

`4095N/m^2`

B

`4800 N/m^2`

C

`480.0 N/m ^2`
