Question

What is the weight of an object of mass 50 kg on Earth and on the Moon?
(Value of g on Earth 9.8 m/s2
, value of ‘g’ on moon = 1.62 m/s2
)

Answer 1

Given:

$Mass = 50 kg \\Acceleration due to gravity on Earth, g = 9.8m/s^{2} \\Acceleration due to gravity on Moon, g = 1.62m/s^{2}$

Find: We have to calculate the weight of an object on Earth and on the Moon

Step by Step Solution:

We have to calculate the weight,

We have the expression of the weight,

$W = mg$

On Earth,

$W = 50\times 9.8\\\\W = 490 N$

On Moon,

$W = 50\times 1.62\\\\W = 81N$

So, the weight of an object on Earth is 490N and on the Moon is 81N
