Astronaut is in a stable Orbit around the earth when he weighs a body of mass 5 kg. What is
the Reading of spring balance
Answers
Answer:
The sense of weightlessness in orbiting satellite is because of the lack of any contact-forces. The only force that acts upon humans in space is the force of gravity, which acts at a distance; but as there is no counter-force, we do not experience the sensation of weight over there. The counter or force-of-contact is missing because everything that floats on space does so due to the acceleration due to gravity being the same. Thus, both the astronaut and the satellite have the same value of g, which is again equal to the centripetal acceleration of the satellite. These two neutralize each other, causing everything to appear weightless.
Concept Introduction:
The pulling force of spring balance is divided by the acceleration due to gravity, is denoted by reading of spring balance.
Given:
We have been given a logical question mentioning that a astronaut is in a stable orbit around the earth when he weighs a body of mass of 5 kg.
m = 5 kg
To Find:
We have to find the reading of the spring balance.
Solution:
There is no gravity in space, so the spring will not be extended.
Final Answer:
The reading of spring balance can't be measured due to no gravity in space.
