3. The force between nucleus and electron is Coulomb force

in vacuum, the interaction force between two static point charges Q1 and Q2 is directly proportional to the proct of Q1 and Q2, and inversely proportional to the square of the distance r between them. The direction of the interaction force is along their line, and the same sign charges repel each other, while the different sign charges attract each other

the electric quantity is Q & # 39; The Coulomb force F of the electron with the action charge of E is f = Ke * q / R ^ 2, where R is the distance from the electron to the nucleus and K is the electrostatic constant

4. Great wisdom is a real-time market display and trading system software
there are many functions, not only transaction information, but also other policies and company information that can be linked
you will know when you use it.
some shortcut keys are also very useful, such as those defined in the K-line state:
F1 is the transaction record of each order in time-sharing; F3 Shanghai index time-sharing chart, F4 Shenzhen index time-sharing chart
F6 select the sector of the stock pool; F7 current affairs information; F8 various K-line change display
f9f12 is transaction entrustment; If you are new to the stock market, it is recommended that you invest a small amount of money first,
wait until you have accumulated experience to a certain extent, and then do it.
