Four electrons are located at the corners of a square 10.0 nm on a side, with an alpha particle at its midpoint.

dimulka [17.4K]

The work done by the Coulomb force will be " $6.08\times 10^{-21} \ J$ ".

Let us define the required work done to move that alpha particle to the one of the mid point of the side length as follows.

→ $W = \frac{4kqQ}{r_1} -(\frac{2kqQ}{r_2} +\frac{2kqQ}{r_3} )$

→ $=2kqQ(\frac{2}{r_1} -\frac{1}{r_2} -\frac{1}{r_3} )$

→ $=2(8.99\times 10^9)(-1.6\times 10^{-19})(2)(1.6\times 10^{-19})$

→ $= (\frac{2}{\sqrt{(5\times 10^{-9})^2+(5\times 10^{-9})} } -\frac{1}{(5\times 10^{-9})} -\frac{1}{\sqrt{(10\times 10^{-9})^2} +(5\times 10^{-9})^2} )$

→ $= 6.08\times 10^{-21} \ J$

Thus the above answer is appropriate.

The properties of element 17 are most similar to which of the following elements?

DedPeter [7]

Halogens are highly reactive nonmetal elements in group 17 of the periodic table. ... Halogens are among the most reactive of all elements. They have seven valence electrons, so they are very “eager” to gain one electron to have a full outer energy level.
