4 . C —Use the following equation to calculate the orbital time period:

The velocity    of  circular    orbit   is

Substituting    the velocity    into    the force   equation,   we  get

Note    that    the mass    of  the satellite   is  not in  the time    period  equation.   This    means   the satellite   mass    does

not influence   the orbital time    period  at  all!
