The weight of an object on Earth is 60 N. What is its weight on the surface of the moon?
10 N
The weight of an object is the force of gravity acting on it. The moon's gravitational pull is significantly weaker than Earth's. The acceleration due to gravity on Earth is approximately \(9.8 \, m/s^2\), while on the moon it's about \(1.62 \, m/s^2\). This means the weight of an object on the moon is about 1/6th its weight on Earth.
We are given that the weight of the object on Earth is 60 N. To find its weight on the moon, we can use the following proportion:
\(\frac{\text{Weight on Moon}}{\text{Weight on Earth}} = \frac{\text{Moon's gravity}}{\text{Earth's gravity}}\)
Let \(W_M\) be the weight on the moon. Then:
\(\frac{W_M}{60 \, N} = \frac{1.62 \, m/s^2}{9.8 \, m/s^2}\)
Solving for \(W_M\):
\(W_M = 60 \, N \times \frac{1.62}{9.8} \approx 9.87 \, N\)
Rounding to the nearest whole number, the weight of the object on the moon is approximately 10 N. Therefore, the correct answer is 10 N.
