Make sure you have batteries that are in a good state of charge in your calculator.
确保你的计算器电池,处在一个良好的状态。
If you look at the ground state in two different systems -If you look at the ground state which is n equals one, think about this, if I increase the proton charge, the Coulombic force of attraction is greater.
如果你观察两个不同系统的基态,当你观察n,等于1的基态时,试想一下,如果我增加质子电荷,相互吸引的库仑力就会更大。
