The buoyant force acting on the ball is 3.8×10³ N .
<h3 /><h3>What is buoyant force?</h3>
If we consider an object which is completely or partially submerged in a fluid. The fluid tends to exert an upward force on the object. This upward force is termed as the Buoyant force.
According to Archimedes principle, the magnitude of buoyant force is expressed as,
B=ρVg
Where,
ρ is the density of the fluid.
V is the volume of the fluid displaced.
g is the acceleration due to gravity
In this part, we need to calculate the buoyant force acting on the balloon. We know that the buoyant force is expressed as,
B=ρVg
Where, ρ is the density of the surrounding fluid, i.e. air, V is the volume of the balloon, and g is the acceleration due to gravity. Therefore the buoyant force will be,
B=ρaVbg
B=1.29 kg/m³×325m³ ×9.8 m/s²
B=3.8×10³ N
