Question

An object weighs 20 newtons when measured on the surface of the earth. What is its weight when measured on the surface of the moon?

Answer 1

1. Given data:

Weight of objects on the surface of the earth $\left(W_e\right)$=20 N.

Weight of the object on the surface of the moon $\left(W_m\right)$=?

2. Calculating the weight of the object on the surface of the moon:

We know that, the weight of an object on the surface of the moon is one-sixth of the weight of that object on the surface of the earth.

$Weightofobjectonthemoon=\frac{1}{6}\times Weightofobjectontheearth$

$W_m=\frac{W_e}{6}$

$W_m=\frac{20N}{6}=3.33N$

Hence, an object weighs 20 N on the surface of the earth weighs 3.33 N on the surface of the moon.
