Question

What would be the weight of a woman on the moon if she weighs 70 kg on the earth? What would be her mass on the earth and on the moon?
(Given g on moon is 1/6th that on the earth)

Answer 1

Answer:

her weight on moon is 11.66 kg.

and her mass remain constant because mass can not change anywhere.

Answer 2

Weight of the woman on moon = 11.67 kg

Mass on Earth & Moon = 7 kg

Explanation:

Given g on moon is 1/6th that on the earth.

Assuming gravity on Earth is 10 m/s2

Weight on earth = 70 kg

Weight = mass * gravity.

Mass on Earth = weight / gravity = 70 / 10 = 7 kg

Mass on moon will be the same as mass on Earth. So mass = 7 kg.

Gravity is 10 / 6 m/s2 on moon.

So weight on moon = mass * gravity = 7 * 10 / 6 = 11.67 kg
