Question

The apparent weight of an object in a satellite that revolves around the earth is zero, it is due to
A) Normal reaction is zero
B) Gravity is zero
C) Both A and B
D) none of these ​

Answer 1

The apparent weight of an object in a satellite that revolves around the earth is zero, it is due to A) Normal reaction is zero.

• When a satellite revolves around the earth, it stays in the orbit due to centripetal force.
• The objects inside the satellite experience a centrifugal force.
• This centrifugal force balances the weight of the object thus making the apparent weight equal to zero.
• Hence, even astronauts feel weightless in a satellite since their apparent weight is zero.
