escape from Earth's orbit?
Does it depend on:
• Initial kinetic energy?
• Mass of projectile?
• Mass of Earth?

If the free atom is released from rest when it is very far away from the fixed atom, what is its minimum distance from the fixed atom?
- r=(L/H) 1/
- r=(2H/L) 1/
- r=(L/2H) 1/
- r=(H/L) 1/
- r=(h/2L) 1/
Two atoms of equal mass, one fixed at the origin (r = 0), interact with a potential energy given by:
U(r) = H/r^8 – L/r^4
where H and L are positive constants.
- r=(L/H) 1/
- r=(2H/L) 1/
- r=(L/2H) 1/
- r=(H/L) 1/
- r=(h/2L) 1/
Two atoms of equal mass, one fixed at the origin (r = 0), interact with a potential energy given by:
U(r) = H/r^8 – L/r^4
where H and L are positive constants. At what separation r is the force between the two atoms zero?
