An infinite thread of charge density `lambda` lies along z-axis. The potential difference between points `A (4, 3, 4)` and `(3, 4, 0)` is

A

`(lambda)/(2pi in_(0))In((sqrt41)/(5))`

B

`(lambda)/(2pi in_(0))In(5)`

C

zero

D

`(lambda)/(2pi in_(0))`

Text Solution

Verified by Experts

The correct Answer is:
C
Equipotential surfaces are coaxial cylinders, therefore `(4, 3, 4)` and `(3, 4, 0)` lie on equipotential surface.
