We consider a small element of length dl with a charge dq since the charge is uniformly distributed on the rod.
The electric field at point P due to charge element, dq is:
The charge element, dq is expressed as:
The figure (Figure 1) shows a thin rod of length L with total charge Q. Find an expression for the electric field E at distance X from the end of the rod. Give your answer in component form. Express your answer in terms of the variables Q, L, X, unit vectors i, j, and appropriate constants.
