Answer

(a) $90V$ (b) $18V$

Work Step by Step

(a) We know that $\Delta V=E\Delta S$ We plug in the known values to obtain: $\Delta V=(1.2\times 10^5)(0.75\times 10^{-3})$ $\Delta V=90V$ (b) We know that $\Delta V=E\Delta S$ We plug in the known values to obtain: $\Delta V=(2.4\times 10^4)(0.75\times 10^{-3})$ $\Delta V=18V$
