Question

The weight of 50 KG astronaut in space is ____________

Answer 1

The weight of 50 KG astronaut in space is O (zero) Newton.

Reason:

• Weight is a type of force calculated by the product of mass and the gravitational acceleration acting on the body.

• Mathematically , its represented as : [ Weight = Mass × g ]

• In space or in satellites , an object does not experience any gravitational acceleration. In other words , they are in zero-gravity.

$\sf{\therefore \: weight \: in \: space = m \times acc.}$

$\sf{ = > weight \: in \: space = 50 \times 0}$

$\sf{ = > weight \: in \: space = 0 \:N }$

Hence , an object experiences WEIGHT-LESS-NESS in space.

Answer 2

Question:-

The weight of 50 KG astronaut in space is ____________

Answer:-

The weight of 50 KG astronaut in space is 0 (zero) Newton.

Explanation:-

• Weight is a force (SI unit : N), which is calculated as W = (m * g)
• Mass is same at all places
• g, (acceleration due to gravity), changes from place to place and that is why weight also changes

Finding value of g in outer space:-

Mass of outer space = M = 0kg

G = 6.67 * 10^(-11) Nm²/kg²

R = distance

$\boxed{\sf{\large{g\:=\:\frac{GM}{{R}^{2}}}}}$

=> g = (G * 0)/R² = 0

=> g = 0 m/s²

Finding weight in outer space:-

W = mg

=> W = 50 * 0 N

=> W = 0N

Ans. W = 0N
