Question

a astronaut has 80kg mass on earth (g=10m/sec square) i)what is his weight on earth? ii)what will be the mass and weight on mars where g=3.7m/sec square?​

Answer 1

$\huge\mathfrak\pink{\underline{\underline{AnSwer}}}$

Weight on Earth = mg

(here, given value of g = 10)

so, weight = 80 x 10 = 800N

Now,

on mars ...

again apply same formula

weight = mg (g = 3.7)

weight = 80 x 3.7 = 296 N

Mass will remain unchanged. ...I.e 80Kg

happy to help!
