Solution

The correct option is C $500 N$
Given:
Mass of the person, $m = 50 k g$
$= 50 k g \times \frac{1000 g}{1 k g}$ = $50000 g$
Since, force exerted by gravity on a $100 g$ body = $1 N$
Force exerted on a $50 k g$ or $50000 g$ person = $50000 \times \frac{1 N}{100} = 500 N$
Hence, the force exerted by gravity on a $50 k g$ person will be $500 N$ .
