Question

Calculate the amount of force exerted by gravity on a person of mass $50kg$.

• A. $500N$
• B. $50$ N
• C. $5N$
• D. $0.5N$

Answer 1

The correct option is A $500N$

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