<u>I have assumed a weight of 120 N on Earth.</u>
Answer:
<em>The object weighs 20 N on the moon</em>
Explanation:
Weight
The weight of an object depends on the mass m of the object and the acceleration of gravity g of the place they are in.
The formula to calculate the weight is:
W = m.g
If g_e is the acceleration of gravity on Earth, and g_m is the acceleration of gravity on the moon, we know:
Dividing by ge:
An object of weight We=120 N on planet Earth has a mass of:
Multiplying by gm:
Substituting the ratio of accelerations of gravity:
Since m.gm is the weight on the Moon Wm:
The object weighs 20 N on the moon
