The weight of a person on the surface of...

The weight of a person on the surface of the Earth is 490 N. Find his weight on the surface of Jupiter and the moon. Also, compare it with his weight on the Earth.
Mass of moon `= 7.3 xx 10^(22)` kg,
Mass of Jupiter `= 1.96 xx 10^(27)` kg,
Radius of moon `= 1.74 xx 10^(6)` m and radius of Jupiter `= 7 xx 10^(7)` m
`G = 6.67 xx 10^(-11) N m^(2) kg^(-2)` ltBrgt Given, `(1)/(1.742) = 0.33 "and ge" = 9.8 m s^(-2)`
