To find the electric field near the midpoint of a uniformly charged plastic rod, we can follow these steps: ### Step 1: Determine the Linear Charge Density The linear charge density (\(\lambda\)) is defined as the total charge (\(Q\)) divided by the length (\(L\)) of the rod. \[ \lambda = \frac{Q}{L} \] ...
