Question

Two charges +q and −q of equal magnitude are placed at the corners A and B of an equilateral triangle. The net electric field at the third corner C

Accepted Answer

C. {'text': 'Is along the direction from A to B (parallel to +q to −q)', 'label': 'C'}

1. Field at C due to +q at A points from A toward C.
2. Field at C due to −q at B points from C toward B.
3. Vector sum has cancellations along the perpendicular bisector of AB and a residual along BA direction.
4. Net field lies along the direction A → B, i.e., from +q toward −q.
