Question 3:

Medium

The International Space Station (ISS) is constantly orbiting the Earth at an approximate altitude of 420 km above the Earth's surface. Knowing that the acceleration of gravity at the Earth's surface is approximately 9.8 m/s², calculate the acceleration of gravity experienced by the astronauts aboard the ISS. Consider the radius of the Earth as 6,371 km.
