Detailed Solution

Weight of an object when measured on the surface of the moon will be

100 N

.
Given data and assumptions:
Mass of an object on the earth,

m_{e} = 60 kg

Acceleration due to gravity on the earth,

g_{e} = 10 m / s^{2}

Weight of the object on the earth,

{= W}_{e}

We know,

W_{e} = m_{e} \times g_{e}

W_{e} = 60 \times 10

W_{e} = 600 N

Thus, the weight of the object on the earth is

600 N

.
We know that,
weight of an object on the moon,

W_{m} = (\frac{1}{6}) \times Weight of the object on the earth

W_{m} = \frac{1}{6} \times 600

W_{m} = 100 N

Thus, the weight of the object on the moon would be

100 N
