Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

We have discussed in lecture that the electric potential at a point near an infinitely long straight
line with evenly distributed charges can only take locations 1 m away as reference and be
calculated by V=-; -In r. Here is the density of charge (charge taken by unit length of
2780
the line), and r is the distance of the point to this line. If right below the point, another point
charge Q with charge q is added (see the drawing), what should be the new relationship between
V and r?
