polawa mada wenna one....

 

[Sun_Boy]

polowa mathu pita = polowa hari mada (i mean guruthwakarshana balaya)

usa anuwa g` wenas weem
g`=(1-2h/r)g

gabura anuwa g` wenas weema
g`(1-h/r)g

ex

g=GM/r2

gravity on earth = 9.80665 m / s2

gravity on center =10.88 m/s2(if my calculations right)

Polawa harimada = 0 (because, m=0 according to F=GMm/R^2 newtons law )

Polawa mathupita = g (9.874562ms^-2)
