Question

An astronaut has 80 kg mass on earth.What is his weight on earth.

Answer 1

W=mg
W=weight
m=mass. and. g=gravitational force
so, W=80 * 9.8
W=784 N

${\boxed{\huge{ {\mathcal{Answer}}}}}$

We know that,

W = mg

where

W = weight and m = mass, g = gravitational force

as we know,

g = 9.8

so,

W = m×g

W = 80 × 9.8

W = 784

hence weight of astronaut on earth is 784
