Question

A motor boat having a length of 10 m and a breadth of 5 cm is floating on a lake. The boat sinks by 5 cm when the load gets on it. What is the mass of the load?

Options

• 3000 g

• 2500 Kg

• 4010 Kg

• None

Answer 1

2500 Kg

Explanation:

According to archimede's principle

weight of load = weight of water displaced by boat

m × 9.8 = (10 × 5 × 0.05) × 9.8 × 10³

m = 50 × 5 × 10⁻² × 10³ = 2500 kg
