In which case of an orbiting satellite if the radius of orbit is decreased

In case of an orbiting satellite, if the radius of orbit is decreased, then (a) its KE decreases (b) its PE decreases (c) its mechanical energy decreases

If radius of an orbitating satellite is decreased , then its kinetic energy

If radius of an orbitating satellite is decreased , then its kinetic energy

The orbital speed for an earth satellite near the surface of the earth 7km-s^-1 ,. If the radius of the orbit is 4 times the radius of the earth is the orbital speed would be
