Question

Two long thin charged rods with charge density lambda

Answer 1

Answer:

Explanation:

Missing question :-

two long thin charged rods with charge density lambda each are placed parallel to each other at a distance d apart. the force per unit length exerted on one rod by the other will be ?

Answer :-

F ( Force on unit length ) = Q (Linear charge density) x  E (electric field)

F ( Force on unit length ) = Q (Linear charge density) x  E (electric field)

F ( Force on unit length ) = λ x E

F ( Force on unit length ) = λ x E

F ( Force on unit length ) =  λ x λ/2Π∈0R

F ( Force on unit length ) = λ²/2Π∈0R
