Question

Find the electric potential VP at point P. [Hint: To input a natural logarithm into the answer box, simply type the letters "ln" (for example ln(x) is the natural logarithm of x).] Express your answer in terms of d, L, Q, and ϵ0.

Answer 1

Answer:

After finding the electric potential VP at point P = Q/Чπϵ₀L ㏑(1+$\frac{L}{d}$)

Explanation:

I believe it is a part C question.  

The derivative of V and P  will be directly proportional to the differential dq and the inverse of Чπϵ₀δ........

Please find detailed solution in the attached picture as i believe that is the answer to the part C question you are seeking for.
