Answer:
0.0006091222 m
Explanation:
q = Charge = 42 pC
V = Voltage = 620 V
= Permittivity of free space = ![8.85\times 10^{-12}\ F/m](https://tex.z-dn.net/?f=8.85%5Ctimes%2010%5E%7B-12%7D%5C%20F%2Fm)
Electric potential is given by (at r = R)
![V=\dfrac{q}{4\pi\epsilon R}\\\Rightarrow R=\dfrac{q}{4\pi\epsilon V}\\\Rightarrow R=\dfrac{42\times 10^{-12}}{4\pi\times 8.85\times 10^{-12}\times 620}\\\Rightarrow R=0.0006091222\ m](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7Bq%7D%7B4%5Cpi%5Cepsilon%20R%7D%5C%5C%5CRightarrow%20R%3D%5Cdfrac%7Bq%7D%7B4%5Cpi%5Cepsilon%20V%7D%5C%5C%5CRightarrow%20R%3D%5Cdfrac%7B42%5Ctimes%2010%5E%7B-12%7D%7D%7B4%5Cpi%5Ctimes%208.85%5Ctimes%2010%5E%7B-12%7D%5Ctimes%20620%7D%5C%5C%5CRightarrow%20R%3D0.0006091222%5C%20m)
The radius of the drop is 0.0006091222 m
Explanation:
Sodium is a chemical element with the symbol Na (from Latin "natrium") and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. ... The free metal does not occur in nature, and must be prepared from compounds.

Which term BEST describes the form of beryllium shown? Protons=4 Neutrons=5 Electrons=2
✓ Ion
Answer:
The answer is C
Explanation:
The radius is HALF of the diameter...so you would have to find a dividing "2". :)
