Question

Calculate the value of the universal
gravitational constant from the
data. Mass of the Earth = 6104 kg,
Radius of the Earth = 6400 km and
the acceleration due to gravity on the
surface = 9.8 m/s2
[Ans : 6.672x10-N m²Kg22]
A body weighs 5.6 kgwt on the surface
of the Earth. How much will be its the
weight on a planet whose mass is 1/7th
mass of the Earth and radius twice that
of the Earth's radius.
[Ans: 9.8 kg-wt]
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: 2.08x10' J]​
