A body is released at a distance far away from the surface of the earth. Calculate its speed when it is near the surface of the earth.?
Verified Answer
A body is released at a distance far away from the surface of the eart...
From the principle of conservation of energy,

12mv2−GMmR=−GMmR+nR
where ‘m’ is the mass of the body and ‘nR’, the height of the body above the surface of the Earth(here nR=2R), ‘M’ and ‘R’, the mass and radius of the Earth respectively and ‘v’, the answer we seek.
Therefore, from the above equation,
12mv2=GMmR−GMm3R
3R since R+nR=R+2R.
Solving, we get,
v=4GM3R−−−−√
But, g=GMR2
Therefore, the velocity of the body on reaching the surface will be,
v=43gR−−−−√
