Jika energy potensial benda a dan b berbanding 3:2, tentukan perbandingan kedua massa jika benda A 10 m diatas Tanah dan benda B 5 m diatas Tanah! ( g = 10 N/kg)

Ep = m.g.h EpA= EpB m. (10 N/kg).10 = m.(10 N/kg).5 m.100 = m.50 100m/50m = 3/2 2m/m = 3/2 m b = 4/3 m a = 1 maka perbandingan massa benda a dan b yakni 1 : 4/3 atau 3 :4

EpA = EpB = 3:2 ma*10 = mb*5 ma*2=mb 2ma/mb = 3/2 m b = 4/3 m a = 1 jadi = ma = 3 / mb = 4 3:4
EpA= EpB
m. (10 N/kg).10 = m.(10 N/kg).5
m.100 = m.50
100m/50m = 3/2
2m/m = 3/2
m b = 4/3
m a = 1
maka perbandingan massa benda a dan b yakni 1 : 4/3 atau 3 :4
ma*10 = mb*5
ma*2=mb
2ma/mb = 3/2
m b = 4/3
m a = 1
jadi = ma = 3 / mb = 4
3:4
