A line charge of 45 nC is uniformly distributed along positive Z axis.Two point charge of 75 nC are located at (3,0,0) and (0,3,0). Determine the potential difference PQ if P is at
(3,4,0) and Q is at (5,4,3).

Hari, the appropriate forum for your revised question is the "Introductory Physics Homework" sub-forum of "Homework and Coursework Questions."

https://www.physicsforums.com/forums/introductory-physics-homework.153/

Please re-post there. First, read the "Guidelines for Students and Helpers" which are posted near the top of that forum. Then, start a new thread, fill out the template that you will see, and show what work and thoughts you have tried already.
