Question

The enlarged circular inset in Fig. 19.11 shows how the positive sodium ions in seawater are accelerated out the rear of the submarine to provide a propulsive force. But what about the negative chlorine ions in the seawater? Because they have charge of the opposite sign, aren’t they accelerated forward, resulting in a net force of zero on the submarine? Explain.
