Question

Aplanet has mass 6.4x1024 kg and radius
3 4x 106 m. Calculate energy required to
remove on object of mass 800 kg from
the surface of the planet to infinity.
[Ans: 1.004 x1010]​

Answer 1

Answer:

1.004x 10^10

Explanation:

Energy required is given by change in gravitational potential energy

GPE=-GmM/R

Where G is 6.67×10^11

M is mass of planet

m is mass of object and

R is radius of planet
