Force Potential Energy Relationship

Q. Calculate the height of the potential barrier for a head on collisionof two deuterons. (Hint: The height of the potential barrier is givenby the Coulomb repulsion between the two deuterons when theyjust touch each other. Assume that they can be taken as hardspheres of radius 2.0 fm.)
