Answer:
The buoyant force =98 N (OPTION A)
Explanation:
Buoyant force refers to whether an object can float in water or air caused by the upward force exerted on a submerged object, which is equal to the weight of the fluid displaced.
Buoyant force is given by:
Fbuoyant = PA
Where, P = pressure
A = area
While, in a situation where there is volume, area and height involved we have:
Fbuoyant = pgha = gpv
Where, p = density of the fluid
g = gravity
h = height of immersed part
a = area
v = volume of immersed part of the body of the fluid
given data:
density = 2g/cm3
volume = 50 cm3
Fbuoyant = gpv
= (9.8m/s²) x (2 x 10∧[tex]-^{3}[/tex] x 10∧[tex]^{6}[/tex] Kg/m³) x (50 x 10∧-[tex]^{4}[/tex] m²) = 98 N
Where, gravity = 9.8m/s²
