Radius of Earth is given as

R = 6.4 * 10^6 m

now here the height from the surface of earth is same as that of radius

h = 6.4 * 10^6 m

now here the acceleration due to gravity at this height is given as

g' = \frac{GM}{(R+h)^2}

g' = \frac{GM}{4R^2}

g' = \frac{g}{4}

now the force of gravity on the given object will be

F = mg'

F = m*\frac{g}{4}

F = 0.5 * \frac{9.8}{4}

F = 1.225 N

<em>so the force of gravity on it is 1.225 N</em>
