Electric field due to a line of charge: HELP!!!!!!!!!!!!!!! 1. The problem statement, all variables and given/known data Positive charge q = 7.81 X 10^-12 C is spread uniformly along a thing nonconducting rod of length L = 14.5 cm or .145 m. What are (a) magnitude and (b) direction (relative to the postive direction of the x axis) of the electric field produce at point P, at distance R = .06 m from the rod along its perpendicular bisector? 2. Relevant equations E = k * (q/(r^2)) dq = lamda * dx replace q with dq 3. The attempt at a solution
Re: Electric field due to a line of charge: HELP!!!!!!!!!!!!!!! Use symmetry and integration to solve. Try drawing the line charge along the y axis, pick a point on the line charge, dq, and express dE at a point P along the x axis created by dq.
