$\huge\bigstar{ \underline{{ \red{a}{ \pink{n}{ \color{blue}{s}{ \color{gold}{w}{ \color{aqua}{e}{ \color{lime}{r}}}}}}}}} \huge \bigstar$

Weight of an object on the surface of the earth is, 

W=mass×acceleration due to gravity=m×g=50×9.8=490N

The weight of 50 kg person at the surface of earth is 490N.

Weight of an object is defined as the gravitational pull exerted by the earth on the object.

Answer 2

Answer:

$\sf {\green {\underline {\red{\underline {♛ \: your \: ༊᭄answer \: ♛࿐ :-}}}}}$

m = 50 kg

g = 9.806 m/s^2

F = mg

. . = 50 × 9.806

. . = 490.34 N [weight of the man]
