Question

6. Consider the situations shown in the figures on this page. Look for symmetry. What can you say about the electric field at the point indicated by the "x'? How can the calculation for the clectric field at this point be simplified by symmetry arguments? Figure What can you say about the compons of E? How can calculation of E be simplified? 31 #2 For this one, tell me what the electric fieldis at point P 12 Assume c uniformly distributed on the bars and there is an equal amount on each bar is Assume charge is uniformly distributed on the x bars and there is an equal amount on each bar

Explanation / Answer

1. The net electric field will be in upwards direction. Due to 3q and 4q the field are in diagonally upward right and diogonally upward left

2. The field due to q will get cancel out. The field due to 2q will be towards left

3. The 5q fields get cancelled. Only due to -12 charge itwill be upwards allong its line.

4. The field will be left direction.

5. the field is zero at that point
