Question

What is the energy on a planet whose size is the same as that of earth and mass 4 times to the energy needed to lift a 2kg mass vertically upwards through 2m distance on the planet is (g=10m/s)

Plz answer this correctly... I will mark u as brainliest

Answer 1

Answer:

Answer 2

Answer:

g=GM/r^2

(G is gravitational constant,M is mass of the planet)

g for earth is 10m/s2

g for planet ....is directly proportional to m

g for planet =4×g of earth

=40

1. potential energy=mgh
2. 2×40×2
3. =160J

hope it helps..
