Question

A geostationary satellite is revolving around the earth. To make it escape from gravitational field of earth, is velocity must be increased

G1 Physics · Accepted Answer

Step 1: Escape requires zero total mechanical energy at infinity: (1/2)mve² = GMm/R, so ve = √(2GM/R). Step 2: Express GM/R through surface gravity/density/radius when needed. Step 3: Take the required ratio or percentage change. Final: B: 41.4%.
