Question

- A cork is immersed in a jar of
water & released. How the cork
will move if the jar is assumed to
be kept in
a satellite orbiting
earth:
​

Answer 1

Answer:

refer to the attachment above

Answer 2

Cork will remain in that position where it left.

Explanation:

1. The magnitude of buoyant force ($F_{b}$) by liquid on object

  $F_{b}=\rho _{l}v_{o}g$        ...1)

  where $\rho _{l}$ =density of liquid.

             $v_{o}$ = displace volume of liquid by object.

             g =gravitational acceleration$(\frac{m}{s^{2}})$.

2. From equation 1) it is clear that buoyant force depend on density of liquid, volume displaced by object and gravitational acceleration.

3. There are no gravitational acceleration  in case of satellite orbiting earth.

4. So cork will feel no buoyant force. After removing external force there will be no force on cork.

5. Because net force on cork acting  is zero. So cork will remain in same position where it was left.
