Answer 2

Aɴꜱᴡᴇʀ

Buoyant Force=10N

_________________

Gɪᴠᴇɴ

Weight of ball = 4 kg

Density of ball = 4000 kgm³

Density of water= 1000 kgm³

Buoyant force?

_________________

Sᴛᴇᴘꜱ

The buoyant force is given by

$\large \sf \orange{f = pgv}$

$\large \sf{}f = \frac{4}{4000} \times 10 \times 1000 \\ \\ \large \pink{ \dashrightarrow{} \tt{}f = \huge \red{10n}}$

Additional information:-

Buoyant : Buoyant force is an upward force exerted by a fluid, which opposes the weight of an object in the fluid. Objects immersed in water observes a loss in weight due to the buoyant force.
