Question

If weight of a body is 50gm on the earth then its weight on a satellite

Answer 1

It will be constant

Because it can be freely movable

Answer 2

The satellite here is our Moon. Objects weigh roughly 1/6 th of what they weigh on the Earth on the Moon.Hence,

50 gm=50/1000 N

=0.05 N on Earth

0.05/6=0.00833333 N on Moon
