Step 1

1 of 2

If the experiment is performed in a small room that is either in a gravitational field of acceleration $g$ or is in a accelerated frame that is accelerating with $g$ that it will produce exactly the same results.

Solution 1

Solution 2

Step 1

1 of 2

A star must bend light in the extent that light cannot escape. Due to this, even light cannot escape nor pass a black hole. Gravitational field of a black hole become so strong that it traps light.
