Question

When a boat is partially immersed in water, it displaced 600 kg of water. How much is the buoyant force acting on the boat in newtons?(g=10 m )

Answer 1

Answer:

For bouyant force we use the formula vρg

here we have m = 600 kg

g = 10m/s

ρ = m/ v

1000kg/ m3 = 600/ v

v = 600 / 1000 = 3/5

Bouyant force = vρg

= 3/5 × 1000 × 10

= 6000 N

Answer 2

GIVEN:

• Mass of the boat = 600 kg
• Acceleration due to gravity = 10 m/s²

TO FIND:

• What is the force of buoyancy of boat ?

SOLUTION:

We have given that the boat displaced 600 kg of water

It means mass of the boat = 600 kg

We know that the formula for finding the buoyant force is:-

$\large{\boxed{\bf{\star \: BUOYANT \: FORCE = Mass \times Acceleration \: due \: to \: gravity\: \star}}}$

According to question:-

• Mass = 600 kg
• Acceleration due to gravity = 10m/s²

$\sf{\longmapsto Buoyant \: Force = 600 \times 10 }$

$\bf{\longmapsto \star \: Buoyant \: Force= 6000 \: N \: \star}$

• Buoyant Force = 6000 N

❝ Hence, the buoyant force of boat is 6000 N ❞
