Statement-1: An astronaut in an orbiting space station above the Earth experiences weightlessness.
Statement-2: An object moving around the Earth under the influence of Earth's gravitational force is in a state of free-fall.
Explanation:
Weightlessness in an orbiting space station:
When an astronaut is in an orbiting space station above the Earth, they experience weightlessness. This is because the astronaut and the space station are both in free-fall towards the Earth. The gravitational force of the Earth pulls both the astronaut and the space station towards it, but since they are moving with sufficient speed, they continuously fall towards the Earth while also moving tangentially to it. As a result, the astronaut and the space station remain in a state of constant free-fall, giving the sensation of weightlessness.
The concept of free-fall:
An object is said to be in a state of free-fall when it is only under the influence of gravity and no other forces are acting on it. In this case, the object is accelerating towards the center of the Earth due to the gravitational force. The acceleration due to gravity near the Earth's surface is approximately 9.8 m/s^2. When an object is in free-fall, it experiences weightlessness because there is no contact force exerted on it to counteract the gravitational force.
Relation between the two statements:
Statement-1 states that an astronaut in an orbiting space station experiences weightlessness, which is true. This is because the astronaut and the space station are in a state of free-fall around the Earth, where the gravitational force is the only force acting on them.
Statement-2 states that an object moving around the Earth under the influence of Earth's gravitational force is in a state of free-fall, which is also true. The object is continuously falling towards the Earth due to the gravitational force, experiencing weightlessness as there are no other forces to counteract the gravitational force.
Conclusion:
Therefore, both Statement-1 and Statement-2 are true, and Statement-2 provides a correct explanation for Statement-1. The sensation of weightlessness experienced by an astronaut in an orbiting space station is a result of the continuous free-fall around the Earth under the influence of Earth's gravitational force. Hence, the correct answer is option A.
