Tolong di Jawab Dengan cara ya -_-

nomor 2
rp = 5 rb
mp = 10 mb
Fb : Fp?

penyelesaian:
Fb / Fp = G.mb/rb^2 / G.10mb/(5rb)^2

Fb / Fp = 1 / 10/25

Fb / Fp = 25 / 10

Fb / Fp = 5 / 2

jadi perbandingannya adalah 5 : 2

nomor 3
Wb = 100 N
mp = 10 mb
rp = 2 rb
Wp?

penyelesaian:
Wp / Wb = mp / mb × rb^2 / rp^2

Wp / 100 = 10 mb / mb × rb^2 / (2rb)^2

Wp / 100 = 10/1 × 1/4

Wp / 100 = 10/4

Wp = 100 × 10 / 4

Wp = 250 N
