Answer
1.1772 N
Step by Step Explanation
Given in the question,
mass of an object = 0.12 kg
To find the weight of this object we will use formula
weight = mass x acceleration due to gravity
We know that acceleration due to gravity on earth is constant = 9.81 m/s²
So,
weight = 0.12 x 9.81
= 1.1772 N
Since it is not mention that were the object is so i assume that it is on earth but if it is on moon then acceleration due to gravity will be 1.625 m/s²
