Practicing Success
Electric field in a region is given by $\vec{E}=(2 \hat{i}+3 \hat{j}-4 \hat{k})$ V/m. The potential difference between points (0, 0, 0) and (1, 2, 3) will be |
2 V 5 V 4 V 6 V |
4 V |
P.d. across the points $=-\vec{E} . \Delta \vec{r}$ $V_2-V_1=-(2 \hat{i}+3 \hat{j}-4 \hat{k}) . (\hat{i}+2 \hat{j}+3 \hat{k})=-2-6+12=4$ volts. ∴ (C) |
