The Total solution for NCERT class 6-12
Abody weighs 63 N on the surface of the earth. What is the gravitational forceon it due to the earth at a height equal to half the radius of the earth?
Weight of the body,┬аW┬а= 63N
Acceleration due to gravity at height┬аh┬аfromthe EarthтАЩs surface is given by the relation:
Where,
g = Acceleration due togravity on the EarthтАЩs surface
Re = Radius of the Earth
Weight of a body of mass┬аm┬аatheight┬аh┬аis given as:
