Question

The picture below shows two circular electrodes, in a plastic tray water bath, similar to the setup that we used in class. the potentials of the electrodes are + 10 V and 0 V, and the equipotential lines shown are 1 V apart. the small grid boxes are 2 cm on a side. Complete the field picture by drawing in the electric field lines. Draw at least 10 field lines and make sure your picture clearly shows the angles between the electric field lines on one hand and the equipotential lines, the electrodes and the insulating water tray on the other hand. Mark the region where the electric field is the most uniform. Mark the region where the electric field is the strongest. What is the direction of the electric field at point A? Clearly indicate the direction by drawing a vector at A.

Explanation / Answer

b) E is most uniform in the mid point between the two the two charges

c) E is strongest in the mid point between the two the two charges

d) E will have direction in the north east direction
