Question

solve the question and explain it

Answer 1

Let the weight of the body be W on the surface of the earth

Radius of the earth = R

Let the height be h, where the weight is $\frac{W}{16}$

As we going away from the surface of the earth, the gravitational force decreases

$W = \frac{GM_e M_o}{R^2}$

Weight at height h:

$\frac{GM_e M_o}{R^2 \times 16}= \frac{GM_e M_o}{h^2}$

$16R^2 = h^2$

h = 4R

Hence, the height is equatl to 4R

Hence, option D is correct
