Gravitational force on the surface of the moon is only 16\dfrac{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?

Answer

Given,

Acceleration due to earth's gravity g = 9.8 ms-2

Object's mass, m = 10 kg

Acceleration due to moon gravity = gm

Weight on the earth = We

Weight on the moon = Wm

Weight = mass x gravity

gm = 16\dfrac{1}{6} ge (given)

So, Wm = m gm = m x 16\dfrac{1}{6} x ge

Wm = 10 x 16\dfrac{1}{6} x 9.8 = 16.34 N

We = m x ge = 10 x 9.8

We = 98 N

Hence, weight on moon and earth = 16.34 and 98 N respectively.
