Question

mi). What is the gravitational potential due to
the Earth at a point which is at a height
of 2R, above the surface of the Earth,
Mass of the Earth is 6x1024 kg, radius of
the Earth = 6400 km and G = 6.67x10-11
Nm²kg.
[Ans: 2.08x107 J]​

Answer 1

Answer:

Mass of body is not given By not considering mass

• Explanation:
• potential energy = - GM/R+h
• given mass of earth = 6×10^24
• gravitational constant 6.7×10^-11
• P.E= 6.7×6×10^24-11/6.4×10^6
• PE=40.2×10^13/6.4×6.4×6.4×10^18
• PE=2×10^7 Joule
