(Figure 1) Part A Identify the regions in which you can find E Check all that apply 0 at a finite distance from the charges between points B and C to the right of point C between points A and B to the left of point A Figure 1 of 1 Subrnit Provide Feedback e to searchExplanation / Answer
Ans:
option 1) Between points B and C
option 4) to the left of point A.
In the above two mentioned regions, the directions of field due to different charges given are in opposite directions, so there is a possibilty of E = 0.
For region between points A and B, E due to all the charges is in the same direction. So, E cannot be zero.
In the region to the right of point C, E due to charges at B and C is to the right while due to charge at point A is to the left but it is too distant to cancel the effects.
