( _Hint_ : Solve this problem by first considering the electric field d\mathbf{\overset{\rightarrow}{\text{E}}} at _P_ due to a small segment _dx_ of the rod, which contains charge dq = \lambda dx . Then find the net field by integrating d\mathbf{\overset{\rightarrow}{\text{E}}} over the length of the rod.)
