A planet has mass, M, and radius R, If the universal gravitational constant is G, what is the expression for the escape velocity of an object on the planet?
√GR2
√2GMR
√2GR
√GMR
Correct answer is B
The expression for the escape velocity ve of an object from a planet of mass M and radius R using the universal gravitational constant G is:
ve=√2GMR
