    The accumulation of snow on the aeroplane may reduce the lift. Explain.

    Answer:

                    Due to the accumulation of snow on the wings of the aeroplane, the shape of the wings no longer remains that of the aerofoil. This reduces the path difference and hence the velocity difference between the layer of air on the two sides of the wings. Hence the pressure difference on the two sides of the wings is reduced. This reduces the uplift on the aeroplane.
