Answer:
N2- N1 = V g
Explanation:
Let's use for this exercised the equilibrium relationship
∑ F = 0
N -W = 0
N = W = mg
Let's use density redefinition
ρ = m / v
m = ρ V
N₁ = (ρ V) g
Repeat for when the liquid is submerged, in this case an upward thrust appears as a result of the water dispensed (rgow)
N₂ + B - W = 0
N₂ = W - B
B = g
= m / V
=
V
N = ρ V g - Vg
N2 = N1 + V g
N2- N1 = V g
