A rod of length L has a uniform positive charge per unit length λ and a total charge Q as shown in figure below. Calculate the electric field at point P. http://www.flickr.com/photos/68849979@N03/6261311950/in/photostream" Been stuck at this question for some time. Could someone point me in the direction as to how should i tackle this question? Great Thanks!! I know I have to solve for both the vertical and horizontal component of E-field. Bu where do i go from there?
