On planet X, an object weighs 5.66 N. On

Question

planet B where the magnitude of the free-fall
acceleration is 1.43 g (where g = 9.8 m/s
2
is
the gravitational acceleration on Earth), the
object weighs 18.46 N.

Answer 1

F = m a = m g
on X :
m gx = 5.66 so gx = 5.66/m
on B
m gb = 18.46 = m * 1.43 * 9.8
so
m = 18.46 / (1.43*9.8)
and
gx = 5.66/m = 5.66 *1.43* 9.8 / 18.46
