1. The problem statement, all variables and given/known data Infinite uniform line charges of 5nc/m lie along the (positive and negative) x and y axes in free space. Find E at :P(0,3,4) 2. Relevant equations E due to line charge along the Z-axis is given by: E=(λ/(2∏*ε*r))*ar where λ=line charge density;ε= permitivity;r=radial distance of point from the line charge;ar=unit vector along the direction of E. 3. The attempt at a solution Here the line charge lies in z=0 plane right??
