Are there supposed to be multiple choices for this question?
<u>Answer:</u> The weight of the object is 29.4 N
<u>Explanation:</u>
To calculate the weight of the object, we use the equation:

where,
m = mass of the object = 3 kg
g = acceleration due to gravity = 
Putting values in above equation, we get:

Hence, the weight of the object is 29.4 N
