Question

how much would a person whose mass is 160kg weight on the moon?? a.9.8N b. 98N c.50N d.500N​

Answer 1

Explanation:

Weight of a body = mg (mass × acceleration due to gravity).

The value of g on Moon is ⅙ th of Earth.

Weight of the person on Earth = (160 × 10) N = 1600 N [ Taking, g = 10 m/s^2]

Weight of the person on Moon = 1600/6 N = 270 N (Approximately).

Answer 2

Given:

Mass of man = 160 kg .

To find:

Weight of man on moon.

Calculation:

Gravitational acceleration of moon is approximately ⅙th times the gravitational acceleration on earth surface.

So, let weight of man be W ;

$\rm{W = mass \times (gravitational \: acc.\:of\:moon)}$

$= > \rm{W = m \times ( \dfrac{1}{6} \times g) }$

$= > \rm{W = \dfrac{mg}{6}}$

Putting available values:

$= > \rm{W = \dfrac{160 \times 9.8}{6}}$

$= > \rm{W = 261.33 \:N }$

So, final answer is:

$\boxed{\bf{Weight \: of \: man \: on \: moon = 261.33 \:N }}$
