Q21 / 208 · NTA Abhyas (NEET) 2020 · Physics · Gravitation

The distance of a geostationary satellite from the centre of earth (radius R = 6400 km) is nearest to

A
18 R
B
10 R
Correct answer
C
7 R
D
5 R

Solution

Distance of geostationary satellite from surface of the earth is approx 36000 km

so from center of earth

distance =

\frac{36000 + 6400}{6400} \approx 7 R

Hence, the correct answer is option: 'C'.
