What is critical velocity ?

Prove that the critical velocity or Orbital velocity for a satellite orbiting. each in terms of density of the earth is 2Rsqrtfrac(2pirhoG)(3) , where rho is the density and R is radius of earth and G is gravitational constant.

What is terminal velocity ?

Show that the critical velocity of a body revolving in a circular orbit very close to the surface of a planet of radius R and mean density rho is 2R sqrt((Gpi rho)/(3)) .

The escape velocity of a body from the surface of the earth is 11.2 km//s . If a satellite were to orbit close to the earth's surface, what would be its critical velocity?

Obtain the relation between escape velocity and critical velocity when satellite is orbiting very close to earth. OR Show//prove that the escape velocity of a satellite orbiting round the earth is equal to sqrt2 time its critical velocity. OR Show that V_e = sqrt2. V_c for a satellite orbiting round the earth.

Solve the following examples/numerical problems : Calculate the critical velocity (Vc) of the satellite to be located at 2000 km above the surface of the earth?

Solve the following examples/numerical problems : Calculate the critical velocity (Vc) of the satellite to be located at 35780 km above the surface of the earth .

Derive the formula for critical velocity (V).

Explain critical velocity for ideal fluid.

If the horizontal velocity is less than critical velocity, then the satellite will travel in
