In question 5 you compared the electric field a t two points

In question 5, you compared the electric field a t two points on the same equipotential line. Now consider two points on different equipotential lines. In figure 6, where is the field stronger m dash point W or point Z? How do you know? Sketch on figure 6 the direction in which a positive charge placed at point Z would move. Sketch the direction in which a negative charge placed at point W would move.

Solution

electric field is stronger when the equi potential lines are closer. Thus electric field is stronger at point W.

force on plate is along the direction of electric field.towatds left
