Two balls, each of radius R, equal mass
and density are placed in contact, then
the force of gravitation between them
is proportional to
(1) F ∝ (1/R^2 )
(2) F ∝ R
(3) F ∝ R^4
(4) F ∝ (1/R)
For a geosynchronous satellite of
mass m moving in a circular
orbit around the earth at a constant
speed v and an altitude h above
the earth surface.Show the
velocity v=(((GM_e )/(R_e +h)))^(1/2) .
If the satellite above is synchronous
how fast is it moving through
space,taking the period to be 24hrs
and M_e =mass of the satellite and
is equal to 5.98×10^(24) kg
