Nomor 1 dan 2 dijawab plzzz

1). Dik = F1 : 20N
A1 : 30cm^2(pangkat)
A2 : 900cm^2

Dit = F2 ...?

Penye =
[tex] \frac{f1}{a1} = \frac{f2}{a2} [/tex]

[tex] \frac{20}{30} = \frac{f2}{900} [/tex]

[tex] \frac{20}{30} \times \frac{900}{f2} [/tex]

[tex] \frac{18000}{30} = \frac{30f2}{30} [/tex]

[tex]600 = f2[/tex]

2). Dik = F2 : 16000
A1 : 50
A2 : 4000
Dit = F1...?

Penye =
[tex] \frac{f1}{a1} = \frac{f2}{a2} [/tex]

[tex] \frac{f1}{50} = \frac{16000}{4000} [/tex]

[tex] \frac{f1}{50} \times \frac{4000}{16000} [/tex]

[tex] \frac{4000f1}{4000} = \frac{800000}{4000} [/tex]

[tex]f1 = 200[/tex]

*maap klo salah:)
