Question

A space laboratory whose mass is 2 × 10³ kg is transferred from an orbit of radius 2R to an orbit of radius 31? Calculate the work done. Here, R = 6400 km (Earth’s radius).

Answer 1

Mass of Earth = M; mass of laboratory m = 2 × 10³ kg;
r₁ = 2R; r₂ = 3R?; W = ?;
R = 6400km = 6.4 × 10³⁶ m
The work done in transferring the laboratory
