Download Solution PDFThe correct answer is option 3) i.e. weightlessness
CONCEPT:
- Weight: The weight of an object is the force with which it is pulled by gravity.
- Mathematically, the weight of an object W = mg
Where m is the mass of the body and g is the acceleration due to gravity.
- Weightlessness: Weightlessness is a phenomenon experienced by a body in the absence of any forces acting on it.
EXPLANATION:
- The outer space has no gravity and thus, there is no pull exerted due to gravity. This means that there is no weight experienced by an object in space.
- Also, the vacuum of space also prevents any sort of air resistance or drag force to act on the body.
- So, a body in space experiences no forces on it. Hence, an astronaut in space experiences weightlessness.
