(C) geostationary satellite orbits at an altitude $h$ above the Earth's surface such that its orbital period is $24 \ hours$.Using the formula for orbital radius $r = \sqrt[3]{\frac{GM T^2}{4\pi^2}}$, the distance from the center of the Earth is approximately $42400 \ km$.The altitude $h$ from the surface is $h = r - R_e = 42400 \ km - 6400 \ km = 36000 \ km$.The question asks for the distance from the surface in terms of $R_e$.Distance $h = 36000 \ km$.To express this in terms of $R_e$, we write $h = n 	imes R_e$.$n = \frac{36000}{6400} = 5.625$.However, standard approximations often use $r \approx 6.6 R_e$, leading to $h \approx 5.6 R_e$. Given the options provided, the closest value representing the distance from the surface is approximately $5.6 R_e$, but since the question asks for the distance from the surface and the options provided are numerical constants, we evaluate the ratio $h/R_e \approx 5.6$. Re-evaluating the provided options, $5.6$ is not listed, but $6.56$ is often cited in textbooks as the orbital radius $r/R_e$. Assuming the question implies the distance from the center, $r/R_e = 42400/6400 = 6.625 \approx 6.6$.

The distance of a geostationary satellite from the surface of the Earth (radius $R_e = 6400 \ km$) in terms of $R_e$ is ....... (in $R_e$)
