If the change in the value of 'g atthe surface of the earth is same as at a depth xbelow it, then (x and h being much smaller thanthe radius of the earth)(1) x = h(2) x=2h(3)x = 2(4) x=h2 |

Answer» Gravity changes at height h and under ground x.As g = GM/R2When R changes then g also changes.Now gh= g(1-2h/R)and gx= g(1-x/R)When ghand gxare same then gh =gxor g(1-2h/R) =g(1-x/R)So 2h/R=x/RSo 2h = x |
