    Answer: A

    0.485 Kg

    Explanation:

    Since the iron weight is motionless, the magnitude of tension T in the string will be equal but opposite to the magnitude of the weight W.

    T = W

    Where W = mg

    T = mg

    Where T = 4.75 N, g = 9.81m/s^2

    4.75 = 9.81m

    m = 4.75/9.81

    m = 0.485 Kg

    Therefore, the mass of the iron weight is approximately 0.485 kg
