Researchers measured the strength of the electric field produced by an electric eel by placing electrodes inside the body of a dead prey fish. In one test, a potential difference of 5.6V was measured between two electrodes that were 1.0cm apart. What was the approximate electric field generated by the eel? Express your answer with the appropriate units. The fish's body was 8.0cm across. If the electric field was reasonably uniform, approximately what was the potential difference across the body of the fish? Express your answer with the appropriate units
