Question

21. A person with mass 10 kg ,weighs 100 N on earth. What will be his corresponding mass and weight on moon?​

Answer 1

Answer:

mass on moon = 10 kg

weight on moon = 16.25 N

Explanation:

given data

mass = 10 kg

weight = 100 N

solution

we know that mass remain same when we move anywhere

but weight will change according to gravitational force

because

weight = mass × acceleration due to gravity .........................1

and

acceleration due to gravity on the moon is 1.625 m/s²

so

weight on moon = 10 kg × 1.625

weight on moon = 16.25 N

Answer 2

Answer:

Mass of the person (m) = 10 kg

Weight of the person on earth (w) = mg

                                                  100  = 10 × g

                                                   g = 10 $m/s^{2}$

At moon, the acceleration due to gravity is 1 6/ th  of the acceleration due to gravity in earth Therefore,  acceleration due to gravity on moon:

$g = \frac{1}{6}$ × $g$

$g = \frac{1}{6}$ × $10$

$g= 1.66\ m/s^{2}$

Mass of the person will be the same on moon as that  on earth.

So,  (m) = 10 kg

Weight of the person on Moon’ =

w = 10 × 1.66

      16.6 N
