In an artificial satellite a space traveller tries to fill ink in pen by dipping it in ink . The amount of ink filled in the pen as compared to the amount of ink filled in the earth's surface will be
(A)less
(B)more
(C)same
(D)nil
GIVE VALID REASON FOR YOUR ANSWER IN A WELL DETAILED MANNER!

Dear Student ,
A space traveller on an artificial satellite will be in free fall around the planet it is orbiting . So the ink will not experience any acceleration relative to the plane due to the planets gravity .
On earth the ink gets sucked up by the pen due to capillary action , but it is counteracted by gravity .While in orbit full force of capillary action can be used to suck up ink into the pen .
So here correct option is B .
Regards

On earth the ink gets sucked up by the pen due to capillary action, but is counteracted by gravity. While in orbit the full "force" of capillary action can be used to suck up ink into the pen.
Thus B is correct
