Question

A fish with a mass of 3 kg causes a fishing pole to bend 9 cm. If the amount of bending varies directly as the
mass, how much will the pole bend for a 2 kg fish?​

Answer 1

• given that amount of bending is directly propotional to mass of fish.
• ⇒ bending =K×(mass of fish)
• K= propotionality constant
• 3 Kg fish bends 9 cm.
• ⇒9 cm=K(3kg)
• ⇒K=3cm/kg
• amount of bending for 2kg fish =K×2kg
• =3cm×2kg
• amount of bending for 2kg fish =6cm
