12. Gravitational force on the surface of the moon is only 1/6 as strong as gravitational force on the earth. What is the weight in Newtons of a 10 kg object on the moon and on the earth?

Mass of the object = 10 kg

Weight of the object on earth = \( W = m × g \)

∴ \( W = 10 × 9.8 \)

\( W = 98 N \)

Weight of the object on moon =\( \frac{1}{6} \) th the weight on the earth.

As the gravitational force on the surface of the moon is only \( \frac{1}{6} \) th as strong as gravitational force on the surface of the earth.

∴ Weight of the object on moon \( = \frac{98}{6} \ = \ 16.3 N \)

Weight on earth = 98 N

Weight on moon = 16.3 N
