Why do astronauts in space feel weightless even though there is gravity there. Is it because of the centrifugal force exerted by the earth which balances the centripetal force ?. Is this theory right?

They feel light in space because gravity on moon is 1/4th of gravity on earth... and as weight is directly proportional to the gravity... so our weight becomes 1/4th in the space due to the gravity of moon being 1/4th of earth's gravity.. that's why we feel weightlessness on the moon....

Really? The question was about space, not on the moon. And the force of gravity experienced on the moon is approx. 1/6 of that on earth, not 1/4.
okay.. sry.. i took wrong... sry
OK...... But I think you should check your facts before answering.
OK... I will never repeat such a mistake...

Gravity is inversely proportionate to distance^2, right? So, the effect of earth’s gravity gets weakened. And the force of gravity exerted by the spacecraft and things in it is very small(called microgravity). So, astronauts don’t feel the kind of gravity exerted on them when they are closer to earth’s surface, and therefore, feel weightless in space.
