Binding Energy
Minimum energy to remove mass m from surface of Earth to infinity is:
Select the correct option:
Solution
GMm/R
This is equivalent to the Binding Energy of the object at the surface.
- Potential Energy at surface U=āRGMmā.
- Energy needed to reach U=0 (infinity) is ĪU=0ā(āRGMmā)=RGMmā.
- This refers to the energy required from rest; if already in orbit, the value is different.
