Question

The weight of a person on earth is 490 N. What is his weight in a planet where the acceleration due to gravity is 10 times greater than that earth

Answer 1

Explanation:

given

W= 490N

planet g = 10xg where g= 10m/s²

mass on earth = 490/10

M= 49 kg

now weight on planet = 49 x 10(g)

= 49 x10(10)

= 4900 N

Answer 2

Answer:

4900 N

Explanation:

Weight on Earth = 490 N

g on Earth = 9.8 m/s²

Mass on Earth = $\frac{Weight on Earth}{'g' on Earth}$ = $\frac{490}{9.8}$ = 5 kg

g = 10 x 9.8 m/s²

Since, mass remains same everywhere on every planet, so, mass on Earth is same as the mass on the given planet.

So, Weight on that planet = 10 x 9.8 x 5 = 4900 N

Hope this helps.....
