Question
What is the escape velocity o the object, if the magnitude o $[$ the potential energy per unit mass of the object at the surface of earth is $E$ ?
Step 1
The formula for potential energy is given by $E = -\frac{GM}{r}$, where $G$ is the universal gravitational constant, $M$ is the mass of the earth, and $r$ is the radius of the earth. Show more…

The magnitude of the potential energy per unit mass of the object at the surface of earth is E. Then the escape velocity of the object is:
Escape velocity of a body of 1 kg mass on a planet is 100 m/sec. Gravitational Potential energy of the body at the Planet is
The potential energy of an object in the gravitational field of the earth is $E_{p}=m g h .$ What must be the SI unit of $g$ if this equation is to be consistent with the SI unit of energy for $E_{p}$ ?
