Δx2 = 23 cm - 20 cm = 3 cm
F1 = 10 N
ditanya F2
F1 : F2 = k.Δx1 : k.Δx2
10 : F2 = Δx1 : Δx2
10 : F2 = 2 : 3
2 x F2 = 3 x 10
2 x F2 = 30
F2 = 30/2
F2 = 15 N jawaban : D
Δx1 = 22 cm - 20 cm = 2 cm
Δx2 = 23 cm - 20 cm = 3 cm
Ditanya F2..?
Jawab = F1 / F2 = k.Δx1 / k.Δx2
10 / F2 = Δx1 / Δx2
10 / F2 = 2 / 3
2 x F2 = 3 x 10
2 x F2 = 30
F2 = 30/2
F2 = 15 N
Opsi pilihannya adalah D
