Answer:
Mass of object in Earth = 1.96 kg.
Explanation:
We know weight is the product of mass and acceleration due to gravity.
Mass is a constant.
W = mg
On planet X, an object weighs 5.51 N.
[tex]W_X=mg_X\\\\5.51=mg_X[/tex]
On planet B where the magnitude of the free-fall acceleration is 1.08 g (where g = 9.8 m/s 2 is the gravitational acceleration on Earth), the object weighs 20.81 N.
[tex]W_B=mg_B\\\\20.81=m\times 1.08\times 9.81\\\\m=1.96kg[/tex]
Mass of object in Earth = 1.96 kg.
