Answer: Option (a) is the correct answer.
Explanation:
It is known that weight is equal to mass times acceleration due to gravity.
Mathematically, Weight = mass × acceleration due to gravity
Since, it is given that weight is 34 N and it is known value of g is 9.8 m/s.
Therefore, calculate mass of the box as follows.
Weight = mass × acceleration due to gravity
34 N = mass × 9.8 m/s
mass = 3.47 kg
Hence, we can conclude that mass of the box is 3.47 kg.
