360821 Air is streaming past a horizontal aeroplane wing such that its speed is \(120\;\,m/s\) over the upper surface and \(90\;\,m/s\) at the lower surface. If the density of air is \(1.3\;\,kg/{m^3}\), then the difference of the pressure on the two sides of the wing is :-

1 \(409.5\,\;N/{m^2}\)
2 \(40950\,\;N/{m^2}\)
3 \(4095\,\;N/{m^2}\)
4 \(40.95\,\;N/{m^2}\)
