The value of g on the Moon is \(\frac{1}{6}\) of its value on the Earth. An object weighs 60 N on the Earth. What will be its weight on the Moon?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 10 N
Weight is \(W=mg\). The mass of the object stays the same on the Moon, so its weight changes in the same ratio as g.
Weight on the Earth: \(W_E=mg=60\,\mathrm{N}\)
On the Moon g is one-sixth, so \(W_M=m\times\frac{g}{6}=\frac{W_E}{6}\)
\(W_M=\frac{60}{6}=10\,\mathrm{N}\)
The weight is not zero, because the Moon does have gravity, only weaker than the Earth’s.
