1. The problem statement, all variables and given/known data Determine the escape velocity of a planetary body that has a radius 5 times greater than its Schwarzschild radius. 2. Relevant equations Schwarzschild radius=(2GM)/c^2 escape velocity=√(2GM/r) 3. The attempt at a solution v=√((2GMc^2)/(10GM))=√(c^2/5) Is this right?
