1.	A body weight 500 N on the surface of the Earth. How much would it weight half way below the surface of Earth.
Answer» Solution :Weighton SURFACEOF Earthmg = 500 Weight BELOWTHE surfaceof Earthat `d=R/2` From variation of .G. with depth ` g. = g(1-d/R)` ` mg. = mg [ 1 - ((R/2))/R ]= 500 [ 1- 1/2] = 500 [1/2] ` `W. = 250 N `
