Question

a child weight 160n on the surface of the earth calculate the weight of child at a height of 3.6×10^6 from the surface of earth radius of the earth is equal to 6.4×10^6

Answer 1

Answer:

after calculation i will be give answer......

Answer 2

Answer:

Weight of  the child =160 N

                              =x * 9.8 (gravity)

thus,  x=160/9.8

           =16.33 kg

now,

R(radius of earth) =6.4 x 10

distance from the centre =3.6 x 10 + 6.4 x 10

                                        =100

g=GM/R²

 =6.673 x 10⁻¹¹ x 6 x 10²⁴ / 100²

 =38(approx) x 10²⁴⁻¹⁵

 =38 x 10⁹

weight of the child =16.33x38x10⁹
