Question
For an infinite line of charge having charge density λ lying along x-axis, the work required in moving charge q from C to A along arc CA is :
Options
A.
loge√2
loge√2B.
loge√2
loge√2C. loge2
loge2D.
loge
logeSolution
B & C are equipotential and field is conservative,
∴ WCA = WBA . = −
q dr. 
= In 2.
∴ WCA = WBA . = −
q dr. = In 2.Create a free account to view solution
