Answer:
option A
Explanation:
given,
Length of boat = 4 m
width of boat = 2 m
height up to which water is displaced = 1 m
Volume of water displaced by the boat
V = L x B x H
V = 4 x 2 x 1
V = 8 m³
buoyant force acting on the boat
F_b = ρ g V
m g = ρ g V
m = ρ V
ρ is the density of water which is equal to 1000 Kg/m³
m = ρ V
m =1000 x 8
m = 8000 Kg
hence, mass of the boat is equal to 8000 Kg
so, the correct answer is option A
