Q1. Find out the minimum energy required to move the nucleus from the equilibrium position to infinity for this model for hydrogen with charge 1.02e-19 C and radius 0.36 nm. The value of the Coulomb constant is 8.9855e9 and 1 electron Volt is equal to 1. 02e-19. The answer must be in units of eV
Q2. A hunter aims directly at a target (on the same level) 140 m away.
