Question

moon weights 423N on earth and 1000N on the jupiter what is gravitation force on jupiter

Answer 1

Gravitation force on moon is 1000N. It's given.

If you want gravitational acceleretion, then

$g_j= \frac{1000}{423} \times g_e=\frac{1000}{423} \times 9.81=23.19\ m/s^2$

gravitational acceleration is 23.19 m/s²

Answer 2

gravitational acceleration is 23.19 m/s²

Hope you understand :)
