Answer:
6
Explanation:
Number of lines emanate from + 5 micro coulomb is 15 .
They terminates at negative charges that means at - 3 micro coulomb and - 2 micro Coulomb.
the electric field lines terminates at - 3 micro Coulomb and - 2 micro Coulomb is in the ratio of 3 : 2.
So the lines terminating at - 3 micro coulomb
= [tex]\frac{3}{5}\times 15 = 9[/tex]
So the lines terminating at - 2 micro coulomb
= [tex]\frac{2}{5}\times 15 = 6[/tex]
So, the number of filed lines terminates at - 2 micro Coulomb are 6.
The number of lines emanating from the negative charged particles are 9.09 and 6.06 respectively.
How to calculate the number of lines.
In an electric field, the number of lines emanating from a charged particle is directly proportional to the magnitude of the charge. Thus, this is given by this mathematical expression:
[tex]q \;\alpha \;L\\\\q=kL\\\\5=k15\\\\k=\frac{5}{15}[/tex]
k = 0.33.
For the -3.0 μC particle:
[tex]L=\frac{q}{k} \\\\L=\frac{3.0}{0.33}[/tex]
L = 9.09.
For the -2.0 μC particle:
[tex]L=\frac{q}{k} \\\\L=\frac{2.0}{0.33}[/tex]
L = 6.06.
