Question

Mass and weight of an object on earth are 5kg and 49 N respectively. What pwill be their values on the moon? Assume that the acceleration due to gravity on the moon is 1/6th of that on the earth

Answer 1

Hello,

The weight of the object on earth = 49 N
Mass of the object = 5kg

We know that the mass of the object remains same all over the universe under normal circumstances while the weight changes as per the change in the conditions.

Now, we know that weight is a force.
Also,
WEIGHT = MASS * g
So,
5 * g = 49
Or g = 49/5 = 9.8 m/sec²


Now, it is given that g on moon is 1/6 th of the earth

Therefore, the g on moon is equal to
$\frac{1}{6} \times 9.8 = 1.6333333...$
Which is 1.63 (approx)
Now,

Since we know that mass always remains constant, so mass of the object on moon will be 5 kg
And
Weight = mass *g
Weight = 5 *1.63 = 8.15 N

Therefore, the weight of the object on moon will be equal to 8.15 N
Mass will be 5 kg

Hope this will be helping you ✌️
