Question

A body weight 100N on the surface of Earth how much will it weight at a heigh equal to half the radius of earth?​

Answer 1

Heya Mate Your Answer is..!!

For distance between object and centre of the earth we haveAcceleration due to gravity at height  be gh = (R/R + h)^2         

 mg1 = GMm / (R + h)^2gh = GM/(R + h)^2     

Now

gh/g = R^2/(R + h)^2 

or gh = g(R/R + h)^2 

given

h = R/2gh = g(R/R+R/2)^2 gh = g(2R / 3R)^2  = g x 4/9

Acceleration due to gravity at depth = R/2gD = g(1 - D/R)gD = g(1 - R/2/R)  = g/2Wh / WD = gh /gD = 4g/9 / g/2= 4g/9 x 2/g = 8/9 = 0.8888

Hope iT HelP YOu DEaR
