Question
A satellite is orbiting the earth close to its surface. A particle is to be projected from the satellite to just escape from the earth. The escape speed from the earth is ve. Its speed with respect to the satellite
Options
will be less than \[\nu_e\]
will be more than \[\nu_e\]
will be equal to \[\nu_e\]
will depend on the direction of projection.

Solution
will depend on the direction of projection.
For example a body projected vertically requires less escape velocity than a body projected at an angle with the vertical.
