Note Show all your work to obtain full credit Four straightl

Note: Show all your work to obtain full credit. Four straight-line segments of length L have each an equal charge per unit length lambda. distributed uniformly over the length. Determine the electric potential at point P a distance \"b\" from the end of each segments.

Solution

V due to all wire will be same

V = K* *ln ((b+L)/b)

http://physics.bu.edu/~duffy/semester2/d06_potential_line.html

this is the electric potential due to 1 wire

Electric potential due to 4 wires will be 4 times this Value

Answer:

Vtotal = 4*K* *ln ((b+L)/b)

Here value of K is 9*10^9 Nm^2/C^2
