							(a)
The normal force exerted by the astronaut on orbiting space station is zero
(unit the astronaut exerts some muscular force). Therefore the apparent weight
of astronaut in an orbiting space station is zero. Astronaut is called in a
state of weightlessness. This is because astronaut as well as space-ship are
freely falling bodies. Statement – 1 is true, statement – 2 is true and
statement -2 is the correct explanation of statement -1.
