Question

suppose your weight on the surface of the Earth is 600 Newton and you were taken to the height equal to the radius of Earth then what will be there

Answer 1

If earth is taken perfect sphere then acceleration due to gravity on a point at height above earth surface is g’=g* R^2/(R+h)^2 putting values h=R we get g’=0.25 g , mass of body does not change so weight 150 newton
