What's the electronic force

1. I think, ha, it should be the Huafen bitcoin Internet bar in the bitcoin blockchain, which can provide stable futures trading with full coverage of both internal and external markets. I have played for a long time and can get money. It is a platform of conscience.

2. Which virtual currency exchange is safer? The top ten virtual currency trading platforms are: bitcoin China, Ethereum, Monroe, dascoin, reborn, etc
1. Bitcoin China
bitcoin China (BTCC), the first and largest bitcoin trading platform in China, was established on June 9, 2011 and operated by Shanghai satuxi Network Co., Ltd. The team members are mainly from China, Silicon Valley and Europe
bitcoin China provides a reliable trading platform for users to buy and sell bitcoin through RMB
users can also save bitcoin safely in the platform
bitcoin China has achieved the best balance between high security and user convenience
2. Ethereum
Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)
reborn is the base currency of ripple network. It can circulate in the entire ripple network, with a total amount of 100 billion, and graally decreases with the increase of transactions. The operating company of reborn is ripple labs (formerly known as opencoin)
3. Reborn currency
reborn currency is the only common currency in ripple system, which is different from other currencies in ripple system. Other currencies such as CNY and USD can not be withdrawn across gateway. In other words, the CNY issued by gateway a can only be withdrawn in gateway A. if you want to withdraw in gateway B, you must convert it into the CNY of gateway B through the registration function of ripple system. However, reborn coin has no such limitation at all. It is universal in ripple system
the business that the contract can provide is almost endless, and its boundary is your imagination, because Turing's complete language provides complete degrees of freedom for users to build various applications. The white paper gives several examples, such as savings accounts, user-defined sub currencies, and so on
4. Monro
Monro (code name XmR) is an open source cryptocurrency created in April 2014, which focuses on privacy, decentralization and scalability. Unlike many cryptocurrencies derived from bitcoin, monero is based on cryptonote protocol and has significant algorithm differences in blockchain fuzziness< 5. Dascoin
dascoin, formerly known as dark coin, is a technical improvement on the basis of bitcoin. It has good anonymity and decentralization characteristics. It is the first digital currency with the purpose of protecting privacy. You can feel that it is liked by the black market when you listen to its name
the main features of Dashi coin are as follows:
1
2. Instant payment function, with timely arrival and low handling charge;

3. Legal digital currency is also a form of traditional banknotes issued by us. It belongs to the category of M0 and will not change in other nature e to the electronization of banknotes. Recently, digital currency has been tried out in Suzhou and Shenzhen, which is essentially different from the concept speculation of Internet blockchain cryptocurrency and also different from financial derivatives, No, because the issuance of digital currency will not affect foreign exchange management

4. Electrostatic force: F = k * q1q2 / R ^ 2, electric field force F = QE, direction unchanged, Lorentz force F = bqv in magnetic field, direction judged by left-handed rule. Then according to the centripetal force formula, the radius and period of motion can be derived. It seems that radius r = Bq / MV; I can't remember the cycle T. I'm afraid I wrote it wrong for you

5. E = u / d
F = EQ
bring it in, don't know how to ask

6. If you ask about the electrostatic force between two charges, it is the Coulomb force: F = kqq / R ^ 2
gravitation f = GMM / R ^ 2
substitute it into the relevant known quantity for calculation

7. The electric quantity e of electron multiplied by the electric field strength e
F = EE

8. There are two forces, the nuclear force and the Coulomb force. Because of the large distance between the electron and the nucleus, the nuclear force is ignored, mainly the Coulomb force between the charges.
F = kqq / (R ^ 2)
k = 1 / (4) π ε 0, ε 0 is the permittivity in vacuum, if the dielectric is air, k = 9.0 × 10^9 N• m2 ／C2

9. Electric field force divided by electron mass
(what? How to calculate the electric field force? Go to the middle school physics book by yourself)
e = u / L
F = EQ
A = f / M
u is the voltage L is the plate spacing (parallel plate electric field) Q electron quantity
enough

10. There are two forces, nuclear force and Coulomb force. Due to the large distance between electron and nucleus, the nuclear force is ignored, mainly the Coulomb force between charges< br />F=kqQ/(r^2)
k=1/4 π ε 0， ε 0 is the permittivity in vacuum, if the dielectric is air, k = 9.0 × 10^9 N• m2 ／C2
