(a) $0V$ (b) $-4.1\times 10^6V$ (c) $-4.1\times 10^6V$

(a) We know that $\Delta V=-E\Delta s$ We plug in the known values to obtain: $\Delta V=-(6.8\times 10^5N/C)(0m-0m)$ $\Delta V=0V$ (b) We know that $\Delta V=-E\Delta s$ We plug in the known values to obtain: $\Delta V=-(6.8\times 10^5N/C)(6.0m-0m)$ $\Delta V=-4.1\times 10^6V$ (c) We know that $\Delta V=-(6.8\times 10^5N/C)(6.0m-0m)$ $\Delta V=-4.1\times 10^6V$
