The buoyant force exerted on a 6,000-mL toy balloon by the air surrounding the balloon is 52.97N.
<h3>How to calculate buoyant force?</h3>
The buoyancy needed for an object can be calculated using the formula;
B = ρ × V × g
where;
- ρ and V are the object's density and volume respectively
- g is the acceleration due to gravity (9.81m/s²)
B = 6000 × 0.0009 × 9.81
B = 52.97N
Therefore, the buoyant force exerted on a 6,000-mL toy balloon by the air surrounding the balloon is 52.97N.
