Answer:
B. The 55 N cat has less mass than the 110 N dog.
Explanation:
Given;
weight of the cat, W₁ = 55 N
Weight of the dog, W₂ = 110 N
distance between the cat and the dog, d = 2 m
The acceleration due to gravity (g) acting on both animals is the same irrespective of their different positions.
g = 9.8 m/s²
Force of gravity, F = W = mg
where;
m is the mass of the animals
The mass of the cat = m₁ = W₁/g
m₁ = 55/9.8 = 5.6 kg
The mass of the dog = m₂ = W₂/g
m₂ = 110/9.8 = 11.22 kg
Therefore, it can be seen that the mass of the cat is less than the mass of the dog.
