In moving from $A$ to $B$ along an electric field line, the electric field does $6.4 \times 10^{-19} \mathrm{~J}$ of work on an electron. If $\phi_{1}$ and $\phi_{2}$ are equipotential surfaces, then the potential difference $V_{C}-V_{A}$ is Fig. $3.77$ a. $-4 \mathrm{~V}$ b. $4 \mathrm{~V}$ c. zero d. $6.4 \mathrm{~V}$
An eleciron is taken from a point $A$ to point $B$ along the path $A B$ in a uniform electric field of intensity $E=1 \mathrm{C}$ $\mathrm{V}_{\ln }^{-1}$. Side $A B=5 \mathrm{~m}$ and side $B C=3 \mathrm{~m}$. Then, the amount of work done is Fig. $1.129$ a. $50 \mathrm{cV}$ b. $40 \mathrm{cV}$ c. $-50 \mathrm{cV}$ d. $-40 \mathrm{eV}$
