[tex] \dfrac{CE}{2}=\dfrac{3jq}{7}\\
6jq=7CE\\
j=\dfrac{7CE}{6q} [/tex]
Answer
[tex]J= \frac{7CE}{6q}[/tex]
Detailed Explanation
First, let's set up a proportion.
[tex] \frac{CE}{2} = \frac{3jq}{7} [/tex]
Now, solve.
[tex] 7CE=6jq [/tex]
[tex] J= \frac{7CE}{6q} [/tex]
Therefore, the answer would be [tex]J= \frac{7CE}{6q}[/tex]
