Question
An astronaut inside a small space ship orbiting around the earth cannot detect gravity. If the space station orbiting around the earth has a large size, can he hope to detect gravity?
✓

Answer

Yes,
If the spaceship is large enough then the astronaut will definitely detect the Earth's gravity as Gravitational Force on the spaceship is directly proportional to the mass of spaceship so as a mass of bigger spaceship will be large and hence it will experience a noticeable amount of force which can be detected, we know gravitational force on a body is given as
$
F=\frac{Gm_1 m_2}{r^2}
$
Where, F is the gravitational force
G is the universal gravitational Constant
$m _1$ is mass of first body which in this case is earth
$m _2$ is the mass of second body which is the spaceship
and $r$ is the distance between earth and spaceship
so as the mass of spaceship $m _2$ increases the gravitational force experienced by it increases and hence can be detected i.e. Gravity can be detected.
