A near surface earth satellite has cylindrical shape with cross sectional area of`s=0.5M^(2)` and mass of M = 10 kg. It encounters dust which has density of `D=1.6XX10^(-11)KG//m^(s).` Assume that the dust particles are at rest and they stick to the satellite’s front face on collision. Take mean density of earth to be`rho=5500kg//m^(3)`Find the drag force experienced by the satelliten
If the dust extends throughout the orbit, find the change in velocity and radius of the circular path of the satellite in one revolution.

A cylindrical solid of mass 10^(-2) kg and cross-sectional area 10^(-4) m^(2) is moving parallel to its axis (the x-axis ) with a uniform speed of 10^(3) m//s in the positive direction. At t = 0 , its front face passes the plane x = 0 . The region to the right of htis plane is filled with the dust particle of uniform density 10^(-3) kg/m^(3) .
