*b = Bumi

x = Planet X

Wb = 200 N

g = 10 m/s²

Wb = m . g

200 = m . 10

m = 200 / 10

m = 20 kg (massa benda di Bumi)

rx = 2rb (jari-jari planet x = 2.jari-jari bumi)

Vx = 2Vb (volume planet x = 2.volume bumi

ρx = 2ρb

ρx : ρb

2ρb : ρb

Perbandingan ρx dan ρb = 2:1

ρ = m / V

m = ρ . V

mx : mb

ρx . Vx : ρb. Vb

2ρb . 2Vb : ρb . Vb

4ρbVb : ρbVb

4 : 1

Perbandingan massa planet x dan bumi = 4 : 1

Wx = mx . g

Wx = 4.mb . g

Wx = 4.20 . g

Wx = 80 . 10

Wx = 800 N
